Vehicle would stall at low speed, even after dealer claimed they fixed some wirings in the back of engine on 8/28/2000. The engine stall has been an intermittent problem for this vehicle since brand new, first it was a defective alternator then the wirings? this is very dangerous on highway because you do not know when the engine is going to stall. This vehicle also has a exhaust fumes getting into ac intake problem, I suspect a defective hood seal.
There id an exceptional loud nosie when accelerating, vehicle taken to dealership, mechanic stated it was only noise from the exhaust. Cj.
