Fantastic video! I had the same issue on a 2019 Grand Caravan and was able to fix it with these steps shown in this video (same cylinder). Highly appreciate it and am thankful I found it.
2014 Promaster camper same P0301. Changed plug and swapped coil packs but still had the codes so I took it to the dealer since I am on vacation and just had some hand tools in a bag. Dealer offered me ride to where I was staying. Took them a minute to understand I was 700 miles from home and I was staying in the van. After low compression test found metal in the oil screen. Cam bearing failed and now I’m at the beach in a condo while my van gets a new engine.
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. Check engine light went off by itself after I cleaned the throttle body. Also if it's not the throttle body spraying a good throttle body with carburetor cleaner could ruin it. Mine was clearly gummed up and sticky when I pulled it out. It was still running rough when I started it after I cleaned the throttle body but I took it for a test drive and it started running fine before I got to the end of my driveway.
I changed #6. And it's still vibrating bad at 10/20/30 mphs. And replaced coils. Mechanic said need to take Chrysler jeep dodge. Where they'll charge $500 to recode for a half hour job!!!!!!
I have a '14 3.6, good plug, coil, injector and compression. No noise either. Still ruff idle and throws p0301. Going to try hard reset. Could it be the pcm? Thanks!
I have a 2017 Grand Caravan with the same situation only on cyl. 2. I replaced the plugs and coils but still is running rough and pulling the same code. Should I check the rocker arms next since I've become really good at removing the upper intake?
@@HooptiesGarage no tapping noise, some guy mentioned that if they are loose, it could be causing the misfire since that has to do with the valves and stuff.
Ok, finally got back in and replaced all 6 injectors. Man! It is running smooth as glass. But to my dismay, check engine light came back on. Still throwing the same code P0302. Took the upper intake back off just to double check the connections and stuff. Everything is hooked up. 😵
You can check to make sure it's getting power and resistance but to check it accurately a scope would be best, you can also pick up a cheap spark tester and at least get a visual if it's throwing spark
Can an ignition coil be bad and not show a code? My car rough idle. Replace spark plugs,air filter,change motor oil,,clean injectors twice,pcv valve,camshaft position sensors, any clues of what could be the problen? 2012 Chrysler 200 3.6
I went to Dodge dealer and they told me that there's a recall , the compression is bad and that's why those misfire codes ... They want to charge $6000 to fix cylinders , valves ...
Had the same problem same code, changed all the plugs and coils drove great for about a hour then check engine light came back on and started to miss fire, what should i try next?
Is it making any noise like a tapping noise ? You may have a cam/follower issue which is common, also possibly a injector is it a single cylinder misfire or multi?
@@HooptiesGarage i have the same problem on 2014 dodge grand caravan i changed all plugs and cylinder 1 coil pack ran good for about 2 weeks and now engine light came back on and its saying cylinder 1 misfire agian
Hi .. I have a 2013 Dodge grand caravan and has the p302 misfire that don't go away ... I did replace spark plugs, coils, even injectors ... And.still has the same code ...
I even replace ecm computer and still have that code .... Dealer said that there's a recall for a cylinder compression .... Buy my car is running good , not over heating .... Just shaking a little bit ...
Almost cause me around few hundred bucks when i ask my fellow friends if i will be taking it to the mechanic so i tried buying spark plug first cause me 12 dollars worth the try thanks
I have the #2 but it not the spark plug or coil as it was change to brand new and still came back Anyone have a ideal what next on the list of what it can be
Is it making any noise like a tapping noise ? Those engines babe issues with the roller followers. Fuel injector another possibility but I wouldn't fire parts at it maybe get it diagnosed
I've got the same car. Misfire on cylinder #6. Changed the plug and coil and still misfiring. Intake manifold? What's your thought? Knowing that these had some bad heads, especially left ones, everyone Im talking to are saying heads.
Have you checked the fuel injector? Is the drivetrain noisy? These do have lifter issues as well. Before tearing it down for a head I would check the fuel injector, check the resistance on it etc. Second thing I would do is a compression test on it. Also another outside chance is did you check and make sure you were getting power to coil? Possible wiring issue, while less likely again another simple check.
I'm dealing with a misfire on 6 also. I replaced factory plugs that were pretty worn and swapped coil 6 with 3 and still have a code for mis on 6. I dont want to throw a full set of coils at it if it might be compression or an icm issue... time to dig a little deeper. I'll try to post here when I find the issue
@@ryanworks35509 In my case unfortunately it was the head. Exhaust valve was not closing properly. It's a shit show. This is the biggest piece of junk I've ever driven.
I am very desperate for somebody to help me I am disabled and running out of money I took my vehicle to a shop after going to AutoZone and having it throw that 303 code or whatever for cylinder 3 check engine light on scene replace spark plugs or coils anyways long story short took it to mechanic I'm out about $700 already after he did everything and put it in even a fresh synthetic oil change the van ran even worse than before when I took it in then the guy said well maybe it's the injector so replace the injector it did run a little bit better but I did hear a slight Miss still I'm voice texting this hopefully it comes out right anyways after he did that I drove home everything seemed fair I guess I did hear a slight Miss but it was very very slight well the following day starts running like crap and the check engine light comes on I don't know what to do somebody said maybe he put maybe the injector that he put on number three all he replaced was the one injector for number three I asked him do I need to replace all the injectors he said no just number three but it's still throwing the same codes does anybody know what's going on my van is only got 100,000 miles on it just rolled over and it's a 2016 Dodge Grand caravan APV please somebody help I'm at my wits end and he's trying to say I'll it's probably a mechanical problem well how can it be a mechanical problem if it ran fine after you put the injector in and why would it run worse after you put the coils and plugs in it just sounds so fishy to me
Almost impossible to diagnose over the internet it's possible he's changing the wrong coil or there's a wiring issue with it, or like he said mechanical those engines do have issues with their roller followers.
I do what the customer asks me to do and what they can afford not everyone is rich guy this lady worked as a deliver driver and could barely afford the repair I did.
So I am supposed to change their spark plugs and pay for it out of my pocket? Lol you live in a fantasy land, you obviously live in beverly hills, this is St Louis you can only do what they will pay for, I deal with a lot of people that live check to check and just need their cars to run and I have people that will get whatever they need done . But thanks for worrying about my reputation lol.

Old-school method still works pretty awesome
Thanks for sharing 👍
Good diagnostic video, love the format...good stuff
Thank you for the kind comment I appreciate it, I love your channel as well I just found it yesterday and already watched prob 20 videos lol.
Thanks for the video. Helped me diagnosis the problem and fixed it my self
Thank you. This was a lot of help
Great information, thanks.
Great info
Good job on the video
Great vid thank you sir

Sorry to hear that, that sucks
Thank You...
Thanks 👍👍👍
worn spark plugs are the giggest point of failure for coil packs, if a pack goes change it's plug and [preferable change "ALL" the plugs as well
Sounds good except u gotta remove intake so alot more work if it's a 2 4 or 6 as those coils are under the intake but yes very smart

What website did you use to find the diagram?
Ditto, that diagram saved me a whole lotta headache
good information, got number 2 (po 302) so got to take the intake manifold off for this one. :0/
It's a pain in the ass it's designed that way but it's not real bad taking the upper off. About 15 mins or so
I changed #6. And it's still vibrating bad at 10/20/30 mphs. And replaced coils.
Mechanic said need to take Chrysler jeep dodge. Where they'll charge $500 to recode for a half hour job!!!!!!
What's wrong with my Dodge Grand Caravan if it's hard to start turns over for a good while but it's strong
After it sits a while ? I would be looking at fuel issues if that's the case
14:23 i thought you activated the self destruct on the caravan there.
LoL yeah the scan tool makes that noise so you don't forget to take your cable out of the obd2 port.
I have a '14 3.6, good plug, coil, injector and compression. No noise either.
Still ruff idle and throws p0301.
Going to try hard reset. Could it be the pcm?
Thanks!
I doubt it those are known for roller follower issues I would pull valve cover and check that if you know for sure all the other stuff is good
@@HooptiesGarage Thanks! Gonna double check everything ✔

Is it making a tapping noise? Usually those will make the noise, don't rule out fuel injector either.
@@HooptiesGarage no tapping noise, some guy mentioned that if they are loose, it could be causing the misfire since that has to do with the valves and stuff.
Yes that's true but normally if they are that loose you will hear a tapping noise especially on the Chrysler engines
Ok, I will check the injectors, Thanks for your help. I will keep you posted!

Can you check the coil with a voltmeter?
You can check to make sure it's getting power and resistance but to check it accurately a scope would be best, you can also pick up a cheap spark tester and at least get a visual if it's throwing spark

Do you have any tapping noise ? Could be a lifter or cam issue but usually those will accompany a code.
@@HooptiesGarage yes i have.
But not that much.
@@DanielPerez-oc8qs Check motor mounts if you still have the car.

You will have to start checking wiring and ecm signal stuff like that, could also be a roller/cam issue on those engines.
I even replace ecm computer and still have that code .... Dealer said that there's a recall for a cylinder compression .... Buy my car is running good , not over heating .... Just shaking a little bit ...
What to check if misfire stays on #1 after new plugs and coil pack
Fuel injector or possible roller rockers, is the engine tapping at all?
Mine is tapping
Almost cause me around few hundred bucks when i ask my fellow friends if i will be taking it to the mechanic so i tried buying spark plug first cause me 12 dollars worth the try thanks

@@HooptiesGarage no noise just a super small vibration idle play by 100rpm or so
Dealer told me that this cars have a recall about that misfire issues .... They might fit that problem for free
Just found out resent that the piston ring is done it as 90psi on #2 and the others are at 150 ish psi
So need new motor saddly

Just like my Grand Caravan... fuel reads 1/4 tank. Man, I hate buying gas!
replaced spark plug and coil and still misfiring.
Looking at possible roller issue, injector etc

Great video but I don't understand why people cry about removing the upper intake so much it's easy barely an inconvenience....
I agree it really isn't that bad but I think for so many years spark plugs were fairly easy to access so it's more of annoyance .
Speak for yourself, I'm short as fuck
