I have a 97 Jeep Grand Cherokee 2WD 4.0L, automatic transmission, fuel injector. My car has been stalling everyday for about a week. It stalls when the engine is at normal running temperature and has done it while i was accelerating, decelerating, and idling. I have had the spark plugs , spark plug wires, distributor cap, and ignition coil changed since this problem began but it still persists. Can anyone help me please?
