I have a 2010 Jeep Compass Limited...My husband has changed all the spark plugs, coil packs, and the cam/crankshaft sensors. My father has even made sure we had everything changed and it still through the slip light and the engine light. When we crank it up the RPM's will not move when you give it gas sitting in the driveway. After about 20 seconds it starts missing really bad. please help us figure out what is wrong with it.

 

Welcome .. You have posted on the JK Forum, JK's are Wranglers. Wranglers do not have the 4 cyl engine that is in your Compass. There are other Forums that would have members driving Compass & Patriots (Patriots have the same drivetrain). I suggest you post your situation on www.myjeepcompass.com & jeeppatriot.com. Should any members have suggestions they will reply.
