One problem related to check engine light on has been reported for the 1996 Jeep Grand Cherokee. The most recently reported issues are listed below.
The Jeep will die at any given time, place, temperature. Nothing seems to make a difference. The only thing I can get to make a difference on wether it runs or dies in putting pressure by hand on the number three computer plug. No check engine light, no codes no nothing. Just a faulty computer design thats putting myself and my family in dangerous situations on a regular basis.
