Code p0304 and p0300 in my 2012 Chevy Camaro SS Fifth Gen Cylinder Misfire 

So glad it was just something very easy for you. Thanks for watching and my pleasure

Yes sir,,,,,short and sweet. Thanks for watching

So glad it was something simple. Those dang lights cause soooooo much panic when they come on. Thanks for watching

Mine just did this, but before I go and spend hundreds of dollars. Was it just your battery that needed to be replaced, my Service Stabilitrak light came on, but drained my battery. Help please.

@@emiliagarza6477 I have a 2019 ss and mine has been on for 3 days on and off

@@rudyescalera7164 I had to buy a new battery and an alternator. I put it on a code reader and it wasn't really showing much, but later I found out that a so called friend had asked me for a jump, I said ok. Didn't think anything about it. Next thing I know he doesn't need a jump anymore and my I started having issues, of course it didn't hit me until a month later. I called him when I started having issues out of nowhere, his response it's your battery, I'm confused, then he's adamant about its a dead cell. Yeah of course he knew be switched batteries which screwed up my alternator. I'm so pissed cause I had to pay almost 500 for the battery and alternator. I learned real quick how to change my alternator. I struggled, but I did it. As a female you cannot trust anyone. I also fixed my AC.. I changed the blend door and actuator. Spent $38 on parts and some guy tried to tell me I needed an actuator that cost $150.. seriously. So me being a female I can't get help from a man with out getting screwed, without going to dinner first.

I also have a 2013 SS 1LE and I had the same issue happen to my car on my way to work. “Service stabilitrack” came on my dash along with all the other lights similar to this video. I have the car parked at work cooling off, I’m hoping it works it’s self out just enough for me to get home and start working on it. I’ll give you updates on how it goes

304 code covers many different things. Plugs, wires, sometimes the coils, and so on....Def get a second opinion when it comes to something that pricey....Thanks for watching

any update on this? did you get it fixed?

@@__loli9678 not really. I keep pouring some lucas additives . Codes doesnt come back. But I need to check the spark plugs

That is the crazy thing about these cars Greg. Any little thing, sets off a ton of lights and you about have to be a rocket scientist anymore to read even the simplest of codes...LOL Hope it makes it for ya bud

No problem 👍 Thank you so much for watching

Hope it helps. Thanks for watching

Glad it went off for you......If it ever comes back check the wiring on the side of the throttle body. GM has issues there. Loose in the connector. Thanks for watching

More than welcome ....Just trying to help out. Thanks for watching

@@CamaroTime i subscribed to your channel

The service stabilitrac light will come on right after cranking on most of them but goes right out. AS for rough idle, is that after warming up, during warm up or, continuous? The L99?LS3 engines are none to have a random clicking noise in it ....Sounds almost like a plug arcing every once in a while. Thanks for watching

@@CamaroTime why Service Stabilitrak comes on during cranking ? what is the reason ? It do this 8 times from 10 attempts. Rough idle I can feel while warming up (it's normal maybe) and on very hot idle after good racing on highway and then stop at traffic light..It's very similar to unstable engine operation but without misfire codes. You suggest to replace coils and plugs ? Plugs are new Acdelco 1mm gap

You could def try replacing the plugs. I went with NGK plugs myself. My car has a different idle when cold compared to hot. It is kind of like it has a cam lope to it.

@@CamaroTime I'll try thank you. Did you ever tried Ruthenium NGK plugs ?

Now that is weird isn't it? LOL Mine has been fine as well. If it ever happens again though, out come the zip ties and we are going to see a priest!! Thank you so much for watching

msclecarcrzy thanks

Yep. But that requires a scan tool and more time. And we all know people want stuff now.....lol.

Sorry but I have no idea. Thanks for watching

So glad you got it fixed easily. Thanks for watching

Try disconnecting battery for a bit and hook it back up. That will reset it. Then drive for couple of days to see if it comes back on. Never heard of pothole causing it....But stranger things have happened. Thanks for watching

Yes. The codes are weird in today's cars. Most of them are just generic and it takes a genius to figure them out. Glad it fixed yours/ Thanks for watching

That is what they will tell you... And if you have it, that will work just fine. :If" that is the problem. but there are other things you can use that cause no harm. "If" that is the problem........Thanks for watching

@@CamaroTime does this type of spray create more problems down the road?

Very nice.....hanks for the tips. Thanks for watching

That would mean a random misfire on cylinder #6. Standing in front of car odd numbers are on left and even are on right and start lowest , closest to you and go up towards the rear. So the first on the right would be cylinder #2 then next would be #4 and the one you are looking for would be the third one, #6.........I would pull the plug first and check it. If it looks OK then swap the coil with another one. Say, #2 coil.....Then unhook negative cable and drive for a while....See if it goes from 306 to 302...If so, replace the coil. It is bad....

Don't even need that. just stick your hand on the end of the wire and give a slight tug........Even if the wire is not seated all the way it can still ark the voltage. Thanks for watching

I have not . Hopefully someone else can chime in......Buttttt, if it were the lifters it would not change by simply changing out a spark plug. Thanks for watching

I have no idea. Have you checked the plugs and wires on it? Thanks for watching

When you say you changed both I assume you are referring to the MAF and the MAP? Have you given the throttle body a good cleaning? Made sure all connections were tight? Does it have a rough idle? Thanks for watching

@@CamaroTime did all those things sir still no luck

Sorry but without having it here and hooked up to a scanner I honestly can not say......Have you checked all the wires to make sure they are no bare spots which might ground out?????

@@CamaroTime yes sir I did it might be my gas pedal sensor

Very nice. Weird but I hope that is it

Everything on these cars have to be programmed for, "your" car. Even the dang radios. SO to answer your question, yes. Thanks for watching

Good luck. hope it is simple fix! Thanks for watching

But mine goes right back off after it says it it just blinks for a sec

Glad you found it Thanks for watching

The service stabilitrac light? That is really just a generic waring light anyway. When is the last time you replaced your car battery?

Sometimes when you change the battery you have to reset the windows......www.wikihow.com/Reset-a-Car%27s-Automatic-Window-After-Replacing-the-Battery Thanks for watching

Oh no. That sux. Thanks for watching

@Camaro Time vacced it out, chopped out 2" thick ice, (ran a space heater in trunk for 3 hrs).. bone dry, no more issues.

Try disconnecting the negative cable for a little while and hook back up. Should reset everything. There are no sensors for alignment. Thanks for watching

Same except I smacked q curb now I can’t get the light off I can’t figure it out

Yes sir. Thanks for watching

Without being there, it is just too hard to say. it could be a thousand things. Did it not come with any warranty? Probably the battery if it will not do anything at all

Camaro Time we tried a new battery wasn’t charging I’m thinking it’s the alternator

@@teresitaleon160 Good. Glad it is nothing major

Yes sir. IF you have good plugs. These were very worn out and I was just wanting to me sure it worked.

The kicker is, the 304 is just a generic code. Could really be almost anything. But I wanted people to know not to panic when it first comes on and to check this as it did happen to me. Thanks for watching

I would not worry unless it keeps doing it. Thanks for watching

Ah man. That is a hard one. just because it has nitrous does not necessarily mean it was ever used . If I was serious about wanting that car I would call around and talk to local mechanics and find one that will look the car over. And do a compression test. yes, it will cost you a little money. Not sure where you are but around here it can be done from as low as $40 to as high as $100 for a comprehensive checkout......Then , use that for your best judgement

Wow. That is a very tough one. No simple answer without being there in person. I would of course start by checking all fuses and relays.

There really are nothing to look for on these cars. Only thing I know of some people were complaining about the radio losing volume. That' s all. And as for the DOD that only really matters if you aree going up on the HP> Thanks for watching

Camaro Time So if I wanted to do simple bolt ons like kooks headers, a air intake, and a tune, would I then need to disable it or remove it? And thanks for the information!

@@ahmadmorrow2749 Correct. I have the CAI, shorty headers and no tune and mine is just fine. But it is your car so it is totally up to you. I really feel no need in messing with it on my car

Thanks!!! SO glad it could be of a little help. That is the whole intent. Glad someone was able to use it. .Thanks for watching

If you go here and ask for help there are people that work at GM that will hook you up. I just typed in my vin number into the search bar for google and it gave me most of the options

What year? That is typically correct. Thanks for watching

@@CamaroTime 2010

Then that is correct

First time I have heard it happen like that. code U0401 is a generic code that is defined as “Invalid data received - engine control module (ECM), but sometimes as “Invalid Data Received from ECM (Engine/Electronic Control Module) /PCM (Powertrain Control Module) “A””, and is set when a communication fault occurs between two or more control modules.Due to the highly complex nature of modern CAN bus systems the fault can be located almost anywhere in the CAN bus system. However, in cases where there is no sub-code present, the fault is likely to involve wiring issues between the PCM and TCM (Transmission control Module), the PCM and the ABS control module, or the BCM (Body Control Module) and the airbags/seat belt control system. Was that the only code you had?

@@CamaroTime Thanks for your reply, mine is a manual by the way and is also a VF SS (similar if not the same systems/ powertrain to the Camaro). I haven't had any others or that one since, touch wood it stays like that.

There are other things that can cause the code. This was just what caused it in my instance......Thanks for watching

@@CamaroTime what’s up brother What other things can cause the code Mine did it months back so one wire was pinched ran some electrical tape to it and problem was fixed till today again same thing happened 😩 car was good till today battery light came on so bought battery but it was altenator was bad bought one and ran car for an hour And all this started again WhT could it be 😭

First you need to determine if it is the coil, the wires, or the plugs. Then replace whichever is needed. And then depending on mileage, go from there. Thank you for watching

I put NGK plugs in mine when I put on the shorty headers and could not be happier. I am still running OEM plugs but will switch to MSD when I change them. Just because they are red...LOL.....Any of them will work. Only time you really have to worry is when you boost it or throw nitrous on them. Thanks for watching

@@CamaroTime yeah that's all the mods I'm gonna do.. I was thinking OEM spark plugs and so really good spark plug wires I heard of those.. Also some other brands that supposedly give but horse power

The reason the car started vibrating was because it went into limp/safe mode to keep you from tearing things up. Then as the computer re checked things, that is hen the light came on. The stabili trac light can come on for anything. it is just a generic light to let you know you have a problem. It could indeed be the battery. Easy enough to check. If you have access to a volt meter , take the two leads and touch one to each side of the battery. A good battery should have around 12.6 volts. There are sooo many things it really could be but the battery is the leading culprit.

@@CamaroTime what else could you think it can be , I haven't put any real mods on the car ( only a plug in ) to make it run on 8 cylinders and not viable 6 to 8 cylinders , I don't drag race , I hope I didn't blow anything ,. "sob"

@@theblackboxpodcastshow1791 Nah, you did not blow anything. It is man made so it could literally go out on you just driving off the car lot. It be as simple as a sensor that went out to something as big as a timing chain...….

Camaro Time Friend the worst case scenario happened, my motor locked up and it’s gone , had the shop mechanic and a former GM mechanic look at the car and they couldn’t turn the motor over , they said that the motor is siezed up and its going to take real bucks ( money that I don’t have) to either rebuild or replace it 😞😢 it was my daily driver and now I’m screwed, just letting you know bro and thanks so much for your advice it was a pleasure

@@theblackboxpodcastshow1791 Ah man. I am so sorry to hear this. Wish there was something I could do. Is there any warranty left on it?

Excellent. Thanks for the info. Thanks for watching

Hey there; No sir. Coil pack will not prevent it from cranking. It will crank but run rough. Same with the plugs

@@CamaroTime thanks..I just looked at it tonight and now it's making a clicking noise when I close or open the driver door. It's still showing service stability trak.

ken williams what ended up being the issue?

@@kenwilliams9674 did you figure out the problem?

@@franciscomartinez290 the ECU fuse was bad. I changed it out and haven't had a start up issue since. But a week ago my a/c stop working on me so now I'm working on it

LOL...Me too. Thanks for watching

Hoenstly stepping on the gas should have no effect. All hat is doing is opening the throttle body up. And all it does is puts in more air.....Next time, try holding it all the way to the floor for 3 seconds BEFORE trying to start, then let off....What that will do is send a message to the computer telling it to clear a flood situation.......thanks for watching

On the SS I am running Flowmaster shorty headers ( so I do not have to get a tune just yet) and Pypes Pype Bomb cat back. Thanks for watching

P0300 is a random misfire code. Thanks for watching

Yoo....Did you solve your problem??? I just got this "engine power is reduced" message on my 2010 Rs..it won't pass over 2000 Rpms...don't know what could be!

Thank you very much. Just doing my little part to try and help. Thanks for watching

@@CamaroTime hey bud long time viewing you channel, and I just subscribed cuz I had forgotten to for too long I have a question that maybe you can help me with I have to replace the oil sending unit on the back of the engine block. Any tips on an easier way to do it without having to remove the intake manifold? I've tried for days upon days and cannot get it done. I don't trust mechanic shops, nor do I have the extra cash to pay the outstanding prices they've quoted me. Any help, or guides would be greatly appreciated. And keep up the quality content.

@@anus_mcfart3 Hey there. I had to replace the one on my Tahoe. But they are all the same on the LS engines. It can be a pain in the butt first time . I found it easier to lay a blanket on the engine and lay on top of it. Of course be very careful not to break anything . You will need a 27 mm (or a 1 1/16th) deep well socket, a universal swivel, a short 1 inch extension, a 2 inch extension and a ratchet. Go in from the top left corner of the engine (after unplugging the harness ) and lay the socket in there. Take your hand and feel the sensor and guide the socket on (you may actually be able to see the sensor in your application). Then break it loose. Time and patience is your friend. I also recommend putting some tape around all of your sockets and extensions once you get the lengths figured out as the socket is a little heavy and can and will fall off unless everything you have is new. Here is a great video showing how to do it. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-2PRTkFH8xsM.html

@@CamaroTime thank you so much for the reply. I will apply all the information to my attempt at replacing the sensor tomorrow. I thank you again, and hope to see more from you in the future my man. GM vehicles can be a pain at times, but I love em.

More than welcome. Just remember to take your time and go into like, well if it takes me 20 minutes to get the harness off and I take a break, that's OK......

Unless it keeps doing it or stays on, there is nothing to worry about. Could be a thousand and one different things that caused it. Thanks for watching

Why thank you so very much. Thanks for watching

Welcome. Thanks for watching

Or maybe GM has a special policy for the build date on those stock wires? That'd be awesome! Get a brand new set of wires for free. It'd be worth checking anyway. 💭

I did. nothing really to mention. It was weird, but weird seems to follow me my whole life...LOL Thanks for watching

It would be neat. but they would never go for it

@@CamaroTime Yeah, I get that. At least now you know your driver information center works right. Chevy's been lighting the cluster up crazy like that when pcm reads reduced power, I figured all the false lights were just to get the drivers attention. Alot of driver's don't know they can burn their whole car up, driving with a down cylinder on many newer vehicles.

LOL...Crazy isn't it. Thanks for watching

AH man, I hope not

Me to man!

Any update ?

Yeah most codes are generic......Thanks for watching

Yeah, it will put a big lump in the throat when it happens. Could me several things. With scan tools pretty hard to diagnose. Could be a bad plug. Could be a bad sticking injector. Thanks for watching

@@CamaroTime I may have found the culprit. I have an Injen CAI and the breathertube that goes from the valve cover into the Injen was loose and barely in there creating a vacuum leak I'm assuming. This tube is in between the throttle body and MAF sensor. I reattached the tube and used worm screws to tighten down the hose. Would this have caused the running rich issue and stabilitrak to light up? I'm being super cautious about starting it up again after this discovery.

It certainly could have. But, I just do not know if it would only affect one cylinder. Normally something like that will affect more than just 1. There are just sooo many things. A bad O2 sensor can cause your to run rich or lean. A bad catalytic convertor and so on. Did you check all the plugs or just the one?

@@CamaroTime just the one plug and the car only has 1650 miles on it. It sat for quite a awhile (>1yr) before I decided to drive it before winter sets in. Gas is shell 89 non ethanol that was treated about 1.5 yrs ago with star tron fuel stabilizer. I just checked all 6 plugs and they were fouled out. Edit I spent 2 hrs taking them out and cleaning them off with carb cleaner and a bronze brush. I started it up for about a minute or two and could see greyish vapor coming out of the tailpipes. I think I'm just gonna have to drain this gas 😒

Sounds like it...................not fun.

Super easy!! Thank you for watching

On these modern cars, especially the camaro , everything makes all the lights come on...LOL Thank you for watching

Sooooooo, where are your videos?????

I was using really old plugs

Some people like knowing how to get to the point.....Thanks for watching

My God, if you don't like get the hell and find a video of someone who gets right to point. Asshole!

Nope...lOL

Moving too slow for you? Click ahead further in video. Not everyone has the same amount of knowledge. Thanks for watching

@CamaroTime It's not about knowledge my guy. Do you even listen to what your saying? 80 % has nothing to do with the problem. Thanks for the knowledge tho.

Talking about the people watching. One would assume as I did , a grown man (50 years old) would know how to at least put a drill bit in a drill. But I have met one that did not. SO I do my videos as if I am talking to someone that has absolutely no idea . Thanks for watching
