I have a 2001 Jeep Grand Cherokee. 137,000 miles 4.0 liter enging.
The check engine came on and the engine started to idle rough (as if there was a constant miss fire). As I accelerated it was jumpy and rough and the check enging light started to flash. As I got to speed and stayed at a constant speed it smoothed out but when I accelerated it started again.
Could this be a wiring harness problem since it has never been replaced or could it be something else.
have the same problem?
