2002 Liberty won't idle
My wife's Liberty with 3.7 4x4 automatic starts and runs nice and smooth if you give it gas, but letting off the pedal it dies. I used the OBD II scanner and there are no codes. I am thinking fuel filter, it has 80,000 miles and that has never been changed, and she got gas the day before it started this. Unfortunately that's in the tank. Anyone had similar symptoms, or changed their filter before?
