SRT6 - Misfire
SRT6 - Misfire
Friends... Bought an SRT6 coupe in June. Starting the day AFTER my car arrived on the transporter, I've been plagued with a misfire on #2. Bunch of good-rep indie shops said
I'm trying to establish what I need to do to get this bird (needs wings) back on the road. I'm grateful in advance for any help you can offer.
Thanks... Crow13
Super clean, 66k miles, but with a misfire.
MOD NOTE: Moved to appropriate forum.
- (1) it's oiling the plug, therefore bad valve or broken ring. Or,
- (2) a digital compression said valves were remaining open, thus the misfire. All these things are possible, and it all looked pretty dire. But as I went from one shop to another, looking for a definitive diagnosis, I began to see a different picture:
- Runs great one day, next day, the miss is back.
- Or, starts with a miss, drive for 5 minutes, shut down, restart, runs great. Or the opposite: runs great, park for awhile, restart with a miss.
I'm trying to establish what I need to do to get this bird (needs wings) back on the road. I'm grateful in advance for any help you can offer.

Re: SRT6 - Misfire
I'll "GUESS" if you like. You have 2 intake valves per cylinder. Perhaps one is sticking open at times. It could have a broken valve spring and run on all 6 from time to time and then not. It's been suggested already but I'll say it again. Pulling the valve cover and looking may answer all your questions.

Re: SRT6 - Misfire
Dear Pizza guy... that's hopeful. But there's no getting around the intermittent miss. I'm hoping at this point that my tentative diagnosis of electrical fault in the #2 injector is the issue. Isd there a post of you tube vid that shows the process of replacing injectors? What parts involved (besides the injector), ie, which gaskets, et5c. Do I need to change oil in supercharger while removed from the car? Also new serpentine belt?
Thanks... Crow13
