I am hoping that some of you jeep brainiacs out there can help with a suggestion of the problem with my 1992 Jeep Wrangler 4.0 hi-output. Symptoms: backfire from time to time....cuts off when driving, cuts off when idling low (like at stoplights)...however, will start up pretty much immediately after it cuts off. Very slow driving speed seems to avoid the cutoff problem (like 10 to 15 mph).
Since this problem starting about 4 weeks ago, we have put new parts in for: distributor, magnetic pick up, crank shaft sensor, and the ignition switch. The ignition switch was replaced yesterday and I had a full day of excellent ++ engine performance, and today, it began the same problem...cutting off when I was driving, and at intersections when engine slows. Just before cutting off, it "burps" like rough engine performance, and then dies.....any help out there...PLEASE!!
