Chrysler Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is Dan. Does the check engine light ever flash? Does it miss at idle and going down the highway? Thanks.
Does restarting car usually help?
Things that are common to cause a specific cylinder misfire is coil, injector, valves, or a failed PCM which is the main engine computer. A failed PCM is the only thing that would reset when restarting car so as of now that is what it sounds like the problem is. To know for sure next time problem happens you will want to test injector pulse and coil trigger. If either are missing then verify that wire between component and PCM is good, if so replace the PCM. PCM replacement would be around a $500 job at dealer. Let me know if you have more questions or if there is anything else I can do to help. Thanks.
To find out if computer is failing they will need to test during problem which may be kinda hard. Otherwise they can swap around coils/injector to see if misfires move cylinders, if not then assume problem is the PCM. Let me know if you have more questions, thanks.
No problem, let me know how it turns out or if you end up running into questions. Thanks again and have a good evening.
