thank u Soo much I'm ab to do this today and was nervous about it u made me feel much more confident!! thanks Soo much I'm a single mom who has to try to do this myself bc I can't afford the shop. I have misfired in cylinder 2&3 I'm working to fix today! thanks I'll keep u updated on how it goes ...
great video, this is exactly what I needed - dealer does not sell OEM coil boots individually but they are available at local aftermarket auto parts stores. Problem fixed!
Thanks Brother for the tips in this video. I really appreciate your help and willingness to come back to record it! My salute to you and may God bless you!!!
Clicking "Like" even though overall video quality is not so great (e.g. doing things one handed and video freezes sometimes). Clicking "Like" because the important detail about what the coil boot looks like as it's failing is the kind of info that's super helpful that I'm not likely to find anywhere else. Ty.
Wow amazing, you just help save us save tons of money to all Chrysler and Dodge vehicles owners. Crooked shops will steal our money.. Thank you a Million...please keep up this amazing help that you provide. And to all of you out there hit the Thumbs Up button..My friend you 2 Thumbs Up.. God bless be safe..
Ohhhhh, so the coil is arcing out the side of the boot. Insulation deteriorates over time then it takes the path of least resistance which equals no spark. Neat.
wow. To change spark plugs in Grand Caravan 20083.8L is very easy,. In 2013 extremely slow and a lot of work. Did Chrysler hired a Nissan designer engineer? Nissans are like that. Regards from Mexico
I find that by applying a bit of dielectric grease on the inside of the boot, the boot slides all the way down and seets properly over the spark plug assuring a good contact with the spark plug, if not there's a bit of a gap creating an arc
Thank you for the long video on why Miss fires occur I don't I have no idea why this is not getting millions of views oh, you should be getting millions of years for the long video for the spot for the spot of the rubber little bit of rubber taken off it's a long video rubber taken offline video rubber taken offline video rambling mess
dude, i literally just replaced my sparkplugs because of misfires and now theres like a slight misfire every now and then, i think i need to reopen the thing and check the boots
I've just been chasing exactly this. Major misfires from overly worn plugs, replaced plugs, minor misfires. No codes thrown. I actually partially solved the issue by closing the spark gap to .035, but will change the boots now.
I have a 2011. engine started running rough like a misfiring cylinder it was driving jerky and at about 40 km an hour speeding up from stop it got really Jerky like the transmission was dying or something. it gave a p0302 code misfiring cylinder 2. A friend told me to try cleaning the throttle body first and it completely fixed it apparently just cleaning the throttle body won't fix it for long he just told me to try cleaning it to see if that's what it was so I just went ahead and put a new throttle body on it.
HELP!!!! I got a 2013 dodge grand caravan, misfires on cylinder 6, p0306 code doesn't go away, I tried everything new ignition coil new spark plugs, swapped injectors swapped ignition coils around and still getting misfire same cylinder.
Hello, thank you for posting your comment/question. To answer your question, when it comes to fixing problems you can change the parts that are the problem (like the boot on the coil) or replace all the coils just in case which will increase the cost of the repair so depends on the customer budget. So the customer wanted to replace only what it needed. Let me know if you have any other questions. Have a great day and God bless you 🙏
Hello. I am sorry to hear that. Check that the coil is getting power and ground, also, check the compression on cylinder 3 if everything looks good go check injector. Keep me posted
Hi I have dodge grand caravan 2014 with 97K miles, I have p0304 code, I replaced spark plugs and ignition coils, and I still have the same problem, I swap the fuel injectors to see if the problem will go for another cylinder, but its still the same code at the same cylinder, Nothing wrong with it while driving, and no noise at all. The only thing while I’m fully stop what ever on Park or drive I feel a little shake on the wheel steering and the rpm flactuate a little bit between 0.5 and 1 Doesnt touch 0.5 and doesnt touch 1, maybe RPM keeps flactuate slowly between 0.6 and 0.9 or less than that. Any ideas??
@@gqautodiagnostics no not yet I’m going to try this week But I heard something from a friend of mine So maybe there is a rust on the cylinder or its dirty? That will cause misfire error?
Hi I have a 2013 Dodge Grand caravan and have the same problem code p0302 .... We replace spark plugs, boots and coild plus inyector from cilinder 2 . After driving for a while the code came back p0302 .... Do you know what could be? ... In the morning shakes but when I put it in March don't shake .... Only in parking .
Hello. I am sorry to hear about your problem. Have you checked compression on cylinder 2 yet? If compression checks ok, check for vacuum leak on the intake gasket. Also make sure to use OEM (original equipment manufacturer) spark plugs. I hope this helps. Keep me posted.
Hello, thank you for posting your question. It seems that you have covered all the basics, so my recommendation is to check the engine compression in cylinder number two. A good compression should be between 110 (the lowest) to 150 psi. if compression checks ok then you need to check that the ignition coil and the injector are getting the signal from the computer (PCM). I hope these information helps you. Please keep me posted and God bless you.
I replaced spark plugs and boots twice! Still the same thing! It seems to not like to idle When engine is warm and I’m waiting at traffic light! Turn engine off start back up is sometimes fixes it for the trip Some say it’s the cylinder head that is the problem I say then it would do it all the time!!
Hello. I am sorry to hear that you are having problems with your vehicle. How were the spark plugs? They were bad? How many miles are in your vehicle? It can be also be an injector that is going bad. There are other things that can also create a misfire. Keep me posted. God bless
@@gqautodiagnostics The spark plugs looked good considering 280000 kms Because of high miles I replaced all plugs And coils I replaced the first ones myself About a week later my mechanic replaced the cylinder 4 plug and coil because the code said cylinder 4 only misfired He took it for a drive was all good While paying for my bill I had the van running When I got in the vehicle engine light was on again he read the code right away and cylinder 4 again showed misfire A few days later same problem as I first had multiple cylinder misfire !! What I find interesting is why does it solve the miss firing when shutting off and starting back up for that trip ? Next trip same thing over !
Hey guys, can anyone help out? Im thinking about purchasing a 2013 caravan (3.6litr v6) with a 135KM the van has been owned by one owner, who did regular maintenance on it...i've been reading up on them and everyone has mixed reviews but from what i've read the 2013's have a lot of transmission problems anyone have experience with this? anything else to look out for? I did do a test drive and it seemed fine but I was only going about 50/70 km around the city, I did floor it and didn't notice any stuttering or anything of such , however the owner did say when he puts it in ''ECO MODE'' he notices a slight change with the transmission shifting and that it takes awhile to pick up in speed? something along the lines of that, I didn't really understand that but is that normal? I plan on taking it to an mechanic to get it checked out so hopefully everything will be good! THANK YOU!
Hello! I personally own a 2013 grand caravan. And it is a great family car. I would recommend doing a transmission service every 50,000 mile to keep the transmission working well. Keep me posted
I am in the same position. I had p0303 so I changed the ignition coil on that bank, and all 6 spark plugs. Code went away for a week or so but returned. Code only pops up during starting. If i clear the code it'll go away for days, then I start the car one day and it throws the p0303. Car runs great except has a rough start and idle until it warms up
Hello, thank you for posting your question. You should always install/replace gaskets to prevent any vacuum leaks. Keep me posted. Have a great day and God bless you 🙏
Hello. That is a good question. After replacing those items the next thing to check is the coil pack and injectors. Keep me posted. Good luck with your repair and please consider subscribing to the channel and God bless you 🙏 Please co
Hi best regards to all, thanks for the video great analysis. I have the same problem, my Dodge Gran Caravan 2017 have a 102450 Miles, 4 month ago I replaced all Sparks Plug and all Ignition Coils, and de alarm show us 2 days later With the code P0302 - Cylinder #2 I replaced the spark plug and Ignition coils and the Intake Gasket 3 Days ago and light with the same code is on again. I will go to check the compresión and the injector for this cylinder #2. Anything else?
Hello. Thank you for posting your question. I am sorry to hear that you are having issues with your vehicle. You are in the right track check compression and the injector to rule them out. I have to ask, the misfire happens as soon as you start the vehicle, or after a few minutes, after you drove it for awhile? Please keep me posted.
@@gqautodiagnostics got same problem I tried everything, it comes back after driving for awhile. I can barely feel it jerking when coming to a stop with transmission on drive. 2013 Dodge Grand caravan SE, 97k miles on it.
Hello, we have a 2014 dodge caravan. Rough idling and shakes bad when running. Code shows P2317. We changed the spark plugs, 2 coils and pcm, rebuild the engine change the intake cam gasket kit, exhaust manifold gasket kit, 12 rocker arms, 12 lifters and 2 cam shafts. After all still shows error P2317, please help. 🙏
Hello thank you for posting your question. I am sorry to hear that you have problems with your vehicle. Let's start from the beginning. The code that you mentioned is due to a misfire in the engine. Did you use OEM (original equipment manufacturer) spark plugs? If you did we can rule out the plugs and start looking at other areas of the engine. Is compression the same in all cylinders? What is your fuel pressure? Low fuel pressure can cause a misfire issue. Please, keep me posted.
@@gqautodiagnostics thank you for responding. I’m not too sure if they use OEM, however, they are great, helpful and clueless as why the van still misfires. We changed everything, check the injector, rebuild the engine, new pcm. We gave it back to the dealership as we have been so stressed about it, we have spent quite a lot of money and every time we have it, after few hours it begins to illuminate engine light and shakes while driving and idling. Last weekend, it completely shut down and won’t even start. So bad we were traumatized.
@@ddr9025 did the dealership do this work and was it covered under warranty noting if it was a used car or dealership and kilometers/Miles under the power train or extended warranty, all this work was it also covered or paid by you. This misfire problem was it dealt with or all done properly by a dealership or a non dealership shop. OEM is original equipment manufacturer parts, example is Mopar distributes the parts made for their line up vehicles, another channel I would check out is Motor City Mechanic (David) might help you as he is a Mopar specialist for all engines in the Dodge/Ram Line up
We replaced all plugs and coils on my 2013 with 108,000 miles and still misfires at idle but has great acceleration and cruising. Compression is good. Any ideas? TIA.
Vacuum leak or fuel Injection system check that test your pressure or ask a local shop to test you fuel pressure and injectors and search for air leaks on the hoses to the intake.. pull codes and research if the check engine light is on
I got a 2018 71k miles already spent $1500 chasing a number 2 cylinder misfire check engine light. P302 code. First replacement was all plugs and number 2 coil. Check light off for about 1.5 weeks then came back again. Since found oil on plugs decided to do a seal and gaskets replacement and Since had same issue code. Decided to do all the coils . Light will not go off. No other codes except p302. It's marked as permanent on the code reader. And only issue is with the shudder when you are at a light and barely take foot off the brake until you give it gas then running normal. But occasionally on highway once in a while it shudders a little bit if you say aren't giving it a steady foot on the gas pedal. Mechanic says maybe I need to add a fuel injector additive, but I was running e85 in it when the code 1st showed up. So it can't be deposit build up. From what I've read online. Only option still to check is cylinder 2 compression, maybe #2 fuel injector and maybe a small vacuum leak. Last time I had a 2017 gt caravan and that one coded constant p174 codes and spent almost 2k and could not get the light to stay off for less than 1 or 2 days. When the light was off, u drove that bitch to the nearest dealer and traded it in. Now 3 years later 3rd caravan in 7 years and again check engine light run around. I hate these vans but I drive rideshare and they are the most affordable to buy replacing them every few years once these issues occur. This is the1st one to act up check engine light on within the 65k mile range. All the other ones made it to at least 100k or close to it before the bullshit starts. I should just trade it in for a new sienna hybrid. But for 50k. I can buy 3 of these caravans and my payments will be less than a new or used sienna. But at least those Toyota cars last 200k plus miles.
@@THERIDESHAREMINUTEOmg Im having this issue with my 2017. I would like to know if you ended up finding the issue to your 302!! I’ve changed everything coils, spark plugs, wires, injectors, purge valve, throttle body, o2 sensors!!! I’m done and stressing lol SERIOUSLY! 😥
Same issue with cylinder #2 misfire. It started around 80k miles. Now have 132k. Shakes only at idle if no gas. Apparently these were plagued with bad cylinder head casting causing indefinite compression leaks. I've driven mine across country several times with this issue and never been stranded. Just disconnect your upper coolant hose from the engine bc when it shakes, it slowly pulls the hoses off. I double clamped em and never have much problems than rough idle. 2016 GC SE plus
