Have Jeep Questions? Ask a Jeep Repair Expert for Answers
Hello my name is***** am an ASE Master Technician and I am glad to help you out with your question.
You need to get the codes. You could have a misfire due to the overheat.
Sometimes the key dance does not always show the codes. Do you have a scan tool?
what kind of engine noise is it making, a knock?
An overheat can cause major engine damage. I would do a compression test on the motor just to see what you are working with.
It could be a coil pack issue as well, it sounds like you have a misfire.
Check spark, fuel, compression. You can disconnect the coils while its idling to see which cylinder is misfiring.
Sure, no problem have a good night.
