JEEP GRAND CHEROKEE ENGINE PROBLEM

2001 Jeep Grand Cherokee • 170,000 miles

My jeep won't not idle unless you started it up with you foot on the gas I change the battery because it was always dead when you let it sit over night and now it won't start you hear it want to turn over but it doent all the way I don't know what to do.

Go out and drive it. The Engine Computer lost its memory and has to relearn "minimum throttle" before it will know when it must be in control of idle speed. It also might not give you the normal "idle flare-up" to 1500 rpm when you start the engine. To meet the conditions for the relearn to take place, drive at highway speed with the engine warmed up, then coast for at least seven seconds without touching the brake or gas pedals.
