P0302 Explained - Cylinder 2 Misfire (Simple Fix) 

Awesome, this was what I needed - it was just the sparkplug

Great video,, thanks

When my car hit 100,000 miles I noticed the coils started failing one by one. They lasted 20 years. replacing them fixed all the misfire codes

So my car started to shake and took it to autozone for a diagnostic and it came back ignition coils and 2 spark plugs. Do you think I should get that done or because more than one spark plug went I should be concerned?

I have p0302 and p0304 any correlation that would be both of them? Obviously they are on the same side is all I can come up with.

Mine is giving me a p0135 code (afr sensor). Could this sensor being fried cause the misfire? It’s just cylinder 2

Thanks man just a bad spark plug. Went ahead and got all 4 changed out. Cars back up and running.

Ok I have a 2008 Toyota Yaris. Where is the fuel filter and how do I change it?

I had a cod p0302 and it was an easy fix. For the number 2 cylinder, I took the coil off and the plugs out the plugs were loose the coil I changed with cylinder 4 so the problem was loose plugs. Fixed IN 15 min Ram 1500 2014 5.7 L.

is it the line order or the firing order for p0302?

06 ram 5.7 hemi, 2 cylinder miss fire, after I clear the code, run my truck, no check engine light, time frame can be 20 minutes, or 4 hours, but the moment ignition is off, and restarted, code appears.. Engine is running rich at idle, but not when driving, no performance loss, but why is the check engine light not on while driving, after clearing code ?l

Hey! Great video. But the spark plug video referenced the link doesn't work... Help? I'm sure there's other ones out there but this is such a great page I would love it if you would just update your link thanks!

If you guys need help with the leak, take some spray starting fluid. And spray a little bit around the engine until you hear it rev, the. Just find the source by spraying a bit more towards where it's reving. Then you'll find the problem. 2000 Silverado

Hola what number is calibrated to a spark plug for blazer 1999.

Dude great video!! Thanks for breaking it down. I have a gas smell coming from all over my car ac vents and because definitely not igniting the fuel and leaking it out. I think I have a fuel leak somewhere causing the lost compression I cylander 2. Car still starts but faster 2 cranks. I'm hoping it may just be a spark plug.

Informative thanks

Well done.

I have a 2011 Honda Odyssy 3.5 been getting the code 302 changed the spark plugs and it soiled the plug again in 2 weeks so I changed the plug and coil and 2 weeks later got the 302 code again not sure what else It could be

Thank you! I started getting this code after I suffered a coolant leak and an overheat. Never got any white smoke coming out of anywhere, and pulled over immediately after the alarm went off. So now I know where to chase up the issue.

P0303 on my 08 OB when left sitting in garage where humidity is off the charts. Running rough as you'd expect on 3 cylinders. Tried spraying water around wires and coil but no sparklies. Removed the cylinder 3 spark plug tube and there was moisture around the tube. Dried it off and replaced it and all seems fine now. Will need to use some sealant on the tube to prevent moisture infiltration.

Thanks John Snow

im to broke for shops and its not the spark plug, coil pack, wires, compression is good spark is good. still giving me the same code p0302 any advice would be appreciated. this is a 2014 Chrysler town and country

Okay I just had an oil change and I had my spark plugs replaced but the engine light is still coming on and I have these codes on my car which is po 304 op420 and 302 on my 2016 Jeep Patriot

Can you tell me what I have to do

good video .I don't have any friends but I think can I do this by my self thanks friend

hmmmm ....a single bad spark plug is a possible deeper issue but all the plugs bad or worn out most likely indicates its due for a tune up...where im from anyway.

Helpful thx

So which ignition coil is cylinder 2?

I get this code on my VW Scirocco 2.0 tsi. Changed the fuel injector, swapped over plug and coil from cylinder 2 to 4 and vice versa, and the same code still appears. Possibly a vaccum leak? Where would I check for leaks exactly on that engine? Around the intake manifold? Any ideas? Thanks.

Helpful

Full tune up full injectors cleaned tested new coils plugs fuel system cleaned fuel filter but for P0302 just comeback after like 10 seconds of running and cel blinks so haven't been able to use vehicle and I have had it at 6 shops. And the last shop broke more stuff and still says can't figure it out. Starts fine just sounds horrible with vibration. 2015 Fiat 500 pop non turbo.

why would a fuel filter cause only one of the four cylinders to misfire?

Problem with swaping coils is you have to take the intake off, and if you get it wrong, you got to do it all over again like I did

My Honda did this today got a code reader got this code so I changed the spark plugs and nothing changed so what’s next?

This gentleman does a great job explaining the code

Do you think it can be a collapsed lifter? I only changed my spark plugs and coils and nothing else. It’s still having the cylinder 2 misfire and i took it to the dealership and they said it has a collapsed litter and suggested I change all lifters and camshaft.. what do you think?

great ,,,,,thnx

Hey man I have a 2011 Camaro LS and just yesterday I had an engine misfire happen but it ran fine afterwards, just today I took it to Autozone to get it checked out and when I turned it on it struggled and white smoke started coming out. Any clue what this is?

Great full on detail video boss. I know the ignition coils, or the spark plugs aren’t the issue. Would any of the other options be causing a rattle noise when I accelerate about 2000 rpms?

It’s happening in my 5 cylinder lol thanks for leaving us out

What if u have just only 1 ignition coil.my truck only has one.

I have an Audi A4 and I’ve been having a misfire I took it to Audi and they changed some bad injectors , it was still misfiring and they told me I had cam and rocker damage to the cylinder head ... I was wondering if that could cause a misfire ? I also got told I had a bad battery and I’ve heard that can lead to misfires also ?

Question if there is a Vacuum leak why would it only affect Cylinder 2 ? Wouldn’t it be a Random misfire ? Im thinking my problem is a bad Injector. Because my Plugs are Brand New and the Coil for Cylinder 2 is also new. My misfire is random but only in time it’s always #2 and I have periods when it’s fine and out of nowhere SEL comes on and there’s a slight change in idle and over a few days the light will go away and the idle gets better but not perfect.

What if I was speeding then my engine light went on, when I plugged in the obd2 sensor it said cylinder 2 misfire but then the engine light went off and it’s been almost a month and the light hasn’t gone back on, does that mean that the problem no longer exists or it’s jus not reading it now since I plugged the reader in?

My 2011 Chevy Equinox seems to idle odd when I’m at a stop sigh/light codes are Po420 and Po302. I just changed the spark plugs and a vacuum leak I found few weeks back.

What would make oil and number two cylinder

So your saying a fuel filter can cause just one cylinder not to fire? I have good spark plugs. Good coils, did the swap test new fuel injectors. Still no firing in cylinder 2

Nice! Do I need to start the engine after switching the sparkplugs?

My friend has a 2017 Jeep Wrangler 6cyl. It seems to only get this P0302 code after it has been idling for a few minutes, and it idles fine. Would that be a clue as to what specific problem it could be? This is the only code that shows up.

2011 ford f150 xlt with 132,675 miles on it. Thick white smoke, I can feel the miss in the gas pedal. Thick heavy smell of gas while idling in the tailpipe. No water coming from exhaust, and no coolant movement in the radiator while idling

Cool idea..to switch the coil to see if the code changes to another cylinder TY

Can a bad catalytic converter cause a misfire ?

I have a 2002 Chevy Prizm, is this still safe to drive? The car shakes when I’m at a light

My truck acted up and was shaking..had the code..had a tune up down. Truck ran good again except when would come to stop would vibrate a little and code still shows up..what would be the problem?

Hahahaha the final was very epic 🤣

i deed change spark plugs new cables and still do the same problem on cylinder 2 misfire?

And if is not all of this that u mentioned? Could be the ECU?

I have a misfire on #1 and #2 cylinders, any idea what I could be looking at?

Very Shakespearien...

When i hit the pedal to the floor, my chevy cruze acceleration cuts off completely, leaving me stranded..

“Its easy to change spark plug” volkwagen : this guy only knows Chinese engines

I have changed the sparkplug , the coil, injector, still have code po302

I change everything in this problem and still come the same code what u have to do

Whats it mean if its permanent

I have a big slit in my intake boot or elbow. It kinda looks like an accordion. Anyways, I’m thinking that it’s causing a cylinder 2 misfire. What do you guys think ?

I have 1999 Grand Cherokee Laredo 4.0 6 cyl. with P 0302 code from "Odometer key on off three times". If 1 cyl. not firing, then remaining 5 should still run, but with a skip. Why do I die, dead in road and won't start? Sometimes have to sit and wait till it wants to start, sometimes couple hours, sometimes starts right back up. I was told and looked into it, is supposedly a "Crankshaft Position Sensor". Explain please!? And there is this comment from another viewer. ebrandon98 10 months ago P0302 on a 1999 Jeep Cherokee 4.0l 6 HO. Not on the scanner, on the dash. Wouldn't start. Crankshaft position sensor had failed. If you drive a Jeep, moreso the older ones with ODBII, codes are fucking useless.

what if the code comes and go ?

I had this problem happen to me today. Out of no where with no prior signs that something was up, my vehicle began to shake as I was driving. RPM was high, and the car started to become sluggish. When I pulled over to turn off the car and to turn it back on, the car died within seconds, I started it again, and the car died within a few seconds again, and this would keep repeating. I finally tried ruffing the engine immediately after turning the car on, and that would keep the car alive. As long as I kept my foot down on the gas pedal the car would not die. As soon as I took my foot off the gas pedal within seconds the car died. My check engine light is on too. I was finally able to get the car in gear before it died again, and I took my car to autozone to have my check engine light scanned. It showed engine code P0302 Cylinder 2 Misfire. The guy at autozone told me to buy a new ignition coil and plugs. I bought 4 new plugs and ignition coils that cost me around $300. I had a relative put those parts in for me, and the 4 new plugs and ignition coils did not resolve the issue. It's still wanting to die after turning on the car, and I have to keep turning the car on and ruffing the engine until I can finally drive it. The car is sluggish after idling or after a complete stop, but starts to drive normally as I build up speed. I can get my vehicle up to 60-70 mph without any issues. The engine light is on, not blinking. But when I start to slow down to come to a stop, I feel the car vibrating, and jerking me a little at each voom voom voom and you can hear it go voom voom voom (I hope you all know what I mean), but improves during acceleration. At this point, I am thinking the problem is the fuel injector, it's not ignition coil or plugs, and it doesn't matter what ignition coil is in cylinder 2, it's always #2 that is misfiring. I had a friend tell me that it sounds to him that it's the timing belt. Anyways, I am taking my vehicle back to the dealership that I bought it from on Tuesday. I bought it used 22 months ago at around 110,500 miles, and it's at 135,150 miles now. It came with 36,000 mile warranty when I bought it. I hope this is covered under a level 2 warranty otherwise I am SOL if this is hundreds of dollars out of my pocket to fix. Just in case if you are all wondering, my vehicle is a SUV a 2016 Hyundai Santa Fe Sport 2.0T AWD.

Can you do a video on code P0202, please, ASAP.

I have a mercedes c230k and has this code, already did change all the spark plugs and ignition coils but didnt work, the code is still there and my car still feel weak. I haven't change the harness wiring yet, do you thing it would be heads?

When I replace the battery, does the misfire instantly resolve? or do you have to drive it around a bit before the the problem gets fixed?

Can a bad camshaft cause a misfire?

Got a 99 Suburban, code misfire cylinder 2, changed spark plugs and wires... No effect, still misfires.

Could a bad gas cap cause the code P0302?

I never been more confused

2:15 POV: you just paid 26 grand for parts and labor on something that “could have been a spark plug” #p0302 gang

Changed all the spark plugs and ignition coil on one cylinder and I’m still getting the code , now what??

I have a 13 kia soul, 90K, car wouldn't start, dealer replaced spark plugs and fuel injectors and did the pressure test on all four cylinders came back good (170 to 180psi), after a hundred or so miles check engine light came on, I checked with ODB to find P0302 error, did the swap test still no luck. I am gonna call up the dealer again to see what's up.

ok i changed all plugs, swapped the #2 coil with #3 cylinder, also replaced air filter while taken apart. check the vacuum hoses and looked fine. deleted code and ran car for less then 20 miles and engine light came back on. ran diagnostic check again and still shows a p0302 code. what else can i check?

Ok so I’ve changed spark plugs coils fuel injectors an fuel filter I’m lost

Changed spark plugs and wires, still misfiring

I have a strong spark but still misfire cilynder 2 Ford f150 4.2 2003

And what if the car misfires only with petrol but with GAS it runs fine? O2 sensor?

Parts are expensive in the US... damn!

Also ignition coils for my civic are like 35 dollars not 200

Got this code on my 3g eclipse after doing a 130mph pull. I do this normally but guess it didn't like it this time

What kinda car does this guy work on lmao parts ain't that expensive

Cute video. I need friends who can fix cars..lol

100%

Not the plugs or the ignition coil no intake vacuum leak no exhaust leak what next injectors. Compression andd leakdown test passed.

1:05-1:15 cool graphic, but the valves go into the cylinder when they open, not magically into the head 😂

P0302 on a 1999 Jeep Cherokee 4.0l 6 HO. Not on the scanner, on the dash. Wouldn't start. Crankshaft position sensor had failed. If you drive a Jeep, moreso the older ones with ODBII, codes are fucking useless.

I have replaced the coil the spark plugs and spark plug wire done a compression test everything is over $125 on the compression test seems to run good but it still has a p302 permanent code in it and they suggestions it all started out because it had a misfire on number two changed coil but new one in but still has code

Changed all these problems and still misfires. Even changed the fuel injectors... it ran good for about a year then misfires came back smh

Where they find this guy Starbucks? Get into the location of the plug and change it!

Or in a 5 cylinder 😵‍💫

Didn't think to check my air intake. Also your forgot to mention 5 cylinder engines. I drive a golf v5.

Probably misfiring due to the spark plug being upside down

Don’t replace the fuel filter for p0302 unless you have a fuel filter for each cylinder. Which you don’t!
