Anybody know how to diagnose a Check Engine Light on a 98 XJ, 4.0l, Auto??? I spent the day wheelig with no issues. The family and I left on our pilgrimage to Wally World and half way there the check engine light came on. The jeep then wouldn't get out of 2nd gear. Any ideas?? I have a big trip planned and need to get the heep fixed fast and cheap!
Thank you very much in advance, Jeff Oosterhouse
