How I fixed rough idle & misfire code P0302 + Where is PCM ECM ECU Computer on 2014 Chrysler T&C?

*Update. Plugs, coils, fuel injectors, and Gas additives did not fix the Rough Idle, or the engine light on with code saying I had a #2 cylinder misfire. So I elected to do 1 more thing to see if I could fix it before heading to the dealer to spend way more than a person should. The ECU computer I figured, was being affected by heat, so I exchanged it for a refurbished, re flashed one from Flagship One. It instantly fixed my rough idle and the engine light has stayed out. This may not work for you, but it worked for me, so am happy about it, as this car is paid for and works well for carrying my aircraft and pulling my boat. After this change for me, I occasionally still get the misfire code, but I reset it and it goes for months at a time without a misfire. So not 100%, but better. I also found a new battery and cable ends helped as it needs to have good battery at idle to provide spark. If your headlights flicker at idle, you may also need a new alternator or regulator to help keep the voltage up enough to make a spark. Good luck with it. Thanks for watching and stay safe!

Thank you! 🙂🙂🙂🙂 So many pcm videos talk endlessly about diagnosis and programming, then gloss over the physical replacement.. 😡😡

[@NightFlyyer]

Your welcome and thanks kindly.

[@toddahern286]

Thanks for this video, it lead me in the right direction. Have a 2014 T&C with 190K. Rough idle - especially when cold, had P0301 misfire cylinder 1 and would not clear. Replaced plug, coil, rocker arms, performed compression test (in the event it was a valve leak, no audible tick), to no avail. I even got a Chrysler mechanic on JustAnswer and he told me it was the head - needless to say I was crushed - but soldiered on. I know this is poor science (doing more than one thing and not testing variables independently)... Here's what solved it for me: 1.) Carefully unplugged and worked ECM harnesses on and off several times as to re-seat in case of corrosion. 2.) Found every conceivable ground in the engine cavity and removed, wire-brushed and secured(there were three). 3.) Replaced the PCV valve (I doubt it had any effect, but you never know). 4.) Cleared OBDII codes - (basic and advanced). Running fantastic now, not a single miss or hesitation. My wager is on the electrical portion. Hope this helps someone, I've read if the upper end is taken care of and good PM practiced, that the lower end of a Pentastar can go as much as 500K before the timing chain fails. This is my new goal - lol.

[@NightFlyyer]

Right on, and good on you. I also have stated in the video notes that "After this change for me, I occasionally still get the misfire code, but I reset it and it goes for months at a time without a misfire.

[@CommoMike]

As an owner of a 12 Grand Caravan I found this video useful. I got the same misfire code and changed the spark plugs and coil packs and got no more codes. Thanks Mr. Herbert!

[@NightFlyyer]

Yes. I thought I was done after changing the coil packs and plugs, but it didn't work for me, so had to take this next step which appears to be working really well. It idles better than it ever has. Thanks much, Mike.

[@josephgarza9377]

Could a bad pcm be a reason for the car to not start at all?

[@willsmith8586]

​@@josephgarza9377no crank, no start could be a battery that outputs only low voltage, starter relays, starter fuses. Test you battery then; You should be able to jump the starter from the relay box without crawling under the car. If that doesn't work, then remove starter, bench test it. If the starter is good, it's probably the PCM, which is last resort.

[@EMcG-t3r]

My 2008 3.8L had a p0300, p0302, p0340 & p0344 code last year, and I replaced the plugs, wires, ignition coil, camshaft position sensor.....the misfire codes went away but it still ran rough and shifted hard. Last month it had issues starting up, and now this morning I got the dreaded p1607 code for PCM/ECM malfunction. I think its been the PCM all along. Fingers crossed, and feeling hopeful. Thx for your video

[@NightFlyyer]

WOW. Well, lets hope this could fix it. I know that if those connectors on the Brain aren't connected just right, you can get all kinds of erroneous codes. Good luck and thanks kindly.

[@vipertech9108]

Dave I work on Chrysler's for a living and hats off to you for taking that on! I can tell you that I have seen my fair share of misfire faults on the 3.6 and it runs from coil to plugs to injectors to rocker arms to wiped cam lobes to burnt vales and broken valve springs. I have not replaced a PCM for misfire as of yet. Intresting to see if this is the long term fix. Just did a coil on one yesterday and a head last week. If you have to go deeper it gets costly. Good work!

[@NightFlyyer]

Coming from a Pro like you, I really appreciate your comments. So far it is running and idling smoother than it has in a long time. It was 80 here yesterday and I let it Idle a long time, with no issues, so I think it was heat related. The car only has 79k on it, so I was not worrying about heads, or valves. Thanks very kindly.

[@dennyheil7016]

I'm having #2 misfire also...Chrysler already changed the heads under warranty....I've tried switching coils didn't change the misfire on #2. I was thinking about changing the injector next

[@oasisauto]

Hi Dave ....I’ve 2015 t&c 3.6 ( Nov 2014)have the same issue 302 code idle rough hesitated taking off full stop...change spark plugs/ coil #2 oem parts and intake gaskets “upper “ and pc valve as well....all that did not fixed the problem 🤦🏻‍♂️...my extend warranty just expired by 2000 miles ( now 77,000 miles).....not sure what to think next.....how you check the fuel injector.....then my next step is Head pressure test 🤷‍♂️....van drive strong and smooth on the hwy ...what do you think 🤔

[@pilot61F]

ViperTech maybe you can help me out. 2014 T&C, 305 code. New coils & plugs and swapping them around and also swapping injectors around did nothing. Had a friends shop check my work and do compression check. All passed. Their lead mechanic did what he called a PCM/ECM reset by disconnecting the battery and shorting positive and negative cables for 15 minutes, to drain all power out of computer. Did nothing however after I left 3 miles down the road everything went to shit. Missing/skipping and bucking like a bronco, started throwing a bunch of new codes. I think that "reset" messed up the computer. Ordered a replacement from FS1 which still has the misfire on 5 but not throwing any other codes but also has no throttle control. FS1 says I need to do a throttle relearn which I can't find a procedure for and I believe is for if the throttle is not working properly, not for a completely non working throttle. It looks like my cyl 5 miss is caused by the head. Can this head, by the firewall, be pulled without removing the engine? I'm out of ideas

[@vipertech9108]

@@pilot61F believe it or not the misfire can be caused by a bad rocker arm. engine will have good compression and pass leak down test on all cylinders. the roller bearings fail in the rocker arm and it rolls off set and holds the valve open momentarily. One other possibilty is a broken valve spring.Now to answer your question, yes the head can be pulled in the van.The throttle body relearn requires a scan tool with reset capability.

Thank you, thank you. I would have looked for a week to find the unit. It was driving me nuts not being able to find it.

[@NightFlyyer]

Hope it works out for you. Note also, at low idle, my lights flickered, so I changed the battery and cables to make sure there was enough juice to fire the plugs. Also a new alternator may be needed to fix that, if the battery does not fix. It is all quite the challenge for sure. Good luck.

[@moldovanucalin8827]

Same problem here, starts fine but after the shock is off I'm starting to feel the misfires from cil. 2. After it heats up further ~40 min of driving the cil. 2 misfires dissapear but cil 1 and 4 start to misfire apparantly from a coil signal issue (all backed up by VCDS reports) and of course I've changed spark plugs, and spark plug cables, coil pack, injectors, and harness verification all the way to ECM plugs. Thank you for confirming my suspicions, I will try to add some thermal paste between the drivers inside the ECM to the aluminium case since it seems to be a heating issue. This method worked with a swirl valve actuator on a diesel engine

There was nothing electronic left for me to check, and all is good now. Hope your plan works for you.

[@yeslawrence]

In my experience, on properly maintained vehicles, these dang misfire codes are RARELY fixed by replacing plugs, coils and fuel injectors. I have to wonder how many perfectly good plugs, coils and injectors have been tossed by ppl trying to chase a misfire code. If you're only having issues when it's hot out i wonder if there might be something with your MAF or IAC. Back in the day you could simple turn a screw to slightly increase idle which seemed to resolve a lot of idle misses and rough idling in general. These newer cars you need a bi-directional scanner to increase the idle. Or leaving the AC on sometimes increased the load and RPM enough to smooth things out.

Well mine still has a rough idle. I would check the battery cables or the alternator. Some times at low idle, there is weak spark to the plugs, due to low voltage. Plugs can be changed and will probably help and this computer would be the last resort. My light still comes on occasionally and if I reset it, it will be out for many miles, then sometimes come on when idling. It is hard to say, but I am still driving mine about 200 miles a week and it runs good...just idles bad. Good luck with it and be safe.

[@NightFlyyer]

I had not problem with Key Fob. Everything worked great. Also note that an old battery that is low in charge, has those stupid Connectors, or a bad ground on the negative wire will also cause the misfire, as the voltage is too low at idle to fire the coils properly. Hope this works for you.

Like I mentioned in the video notes, I still get the code only once in a while even after changing the ECM. I just keep resetting it. I know it only happens at idle on mine and I notice my lights flicker at idle, so am thinking an alternator or regulator. Some say low compression, but it is high as it is an E85 flex fuel machine, so I dont know on that one.

The mileage is stored in the Speedometer, so it can't be tampered with.

Sometimes the light comes on, at idle, but if I reset it, it will go for weeks with no problem.

Thanks man for your feed back just got my computer today but it didn't do much lights just came on but not the angine I guess the computer wasn't programmed right to my van or vin number didn't match . So I'm hopping I'll get a refund for it 😜,

[@NightFlyyer]

@@thuggmtz Thats a bummer. Check the battery cables and alternator. Low voltage at idle, can cause a misfire as well. Good luck.

Hello question my 2014 chrysler town and country is idling and the engine is like its shivering vibrating and rpm needle goes up and down a little I changed the spark plugs already what can be causing this can it he the brain

[@NightFlyyer]

Well, It helped mine, but not 100%. I changed the battery and cables too, as I think the rough idling on mine may also be from such a low idle, the plugs do not get spark enough. The brain helped me, as I don't get the engine lite much anymore. I changed plugs, coil packs, injectors, battery, and cables and I have been driving it fine. I cant tell if the brain will fix yours, but wish you luck.

@@NightFlyyer thanks for you input 👍 my first time owning a chyrsler t&c I will take it to dealership I still got warranty

[@NightFlyyer]

@@Yahs-our-El Good idea, especially under warranty. Let me know what they do to fix it, if you don't mind. Thanks and good luck.

[@Yahs-our-El]

@@NightFlyyerthey never fixed it and I'm not under warranty no more, they think it's a head gasket issue now im getting misfiring codes before I took it there got it scanned at o'rileys and it was a p0456 I'll probably will do it myself

[@NightFlyyer]

@@Yahs-our-El Ive heard head gasket issues too, but as long as it runs great, I will just reset the light when it occasionally comes on. Of course a piece of black electrical tape over the light will fix it for sure. LOL.

[@ynotdoityourself3288]

I have a p0201 stay on and the p0301 one shows with it . I replaced the coil and the spark plug and checked the wiring . Still no fix so I got a used pcm and it still was showing the p0201 code along with more codes so maybe I need a new one

[@ynotdoityourself3288]

I have a 2.7l dodge magnum hope I new pcm work because the used one didn’t

[@jayguzman874]

You all be very careful on ordering this part from Flagship. I just ordered it put it in and the car turned on but when I pushed my gas pedal the car wouldn’t even Move the gears would change but I could not get no acceleration all bad be careful

[@NightFlyyer]

That is what happens if the connectors aren't plugged in all the way.

Hi Dave, we have a 2016 town and country w/ 85K miles on it. lately my husband noticed that the idle is a little uneven. We're not getting any engine light of warning lights. Just the rough idle. Fuel economy is still ok (18 mpg w/ ac on and 23-35 mpg highway) Still has original spark plugs. Any ideas on what he can do himself.

[@NightFlyyer]

Well mine still has a rough idle. I would check the battery cables or the alternator. Some times at low idle, there is weak spark to the plugs, due to low voltage. Plugs can be changed and will probably help. It is not that hard. Good luck with it and be safe.

Do you have to reprogram the pcm after installing it?

[@joeycracks2011]

Great video, I went on the flagship one website to order the part and the part cost is saying $337.49. 😏. I have a 2011 Dodge Grand Caravan same problem.

[@NightFlyyer]

Thanks. That sounds pretty high of a price. ???

[@NightFlyyer]

PS, a low battery or a bad cable to ground can also cause this.

[@dennisteagueCV41]

just came across this video. But found that the part cost is at $365. Not doable for us either.

Geez resetting the light wasn’t a repair. Who would have thought. Then replacing only 1 spark plug, then just guessing by throwing parts at it Why am I watching this when you don’t know what your doing

[@NightFlyyer]

Chrysler bulletin said it is was the Plug and/or the Fuel injector, or a warped head. I'm 75 and did all this starting with the most easiest. So I changed the fuel injector and the plugs. And all the rear plugs is difficult, and besides I did not get a warning on my OB tester that said I had misfires in all plugs, just #2. That did not work, so I did this.. and it worked. Geez!

Sounds like an expensive gamble to me
