Have Jeep Questions? Ask a Jeep Repair Expert for Answers
Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner past midnight.
What model and engine is this 07 Jeep?
Can you feel the misfire occur?
When starting is there any exhaust smoke noticed?
Do you have a scan tool that can run a power balance test to see which cylinder is weaker than the others?
Compression should be 170-225 so it appears the engine is internally damaged or the engine has jumped time. Does the compression come up when doing a wet test.
Thanks for using Just Answer, and rating me so I am compensated, Chris
