Question

97 Jeep Grand Cherokee Laredo cuts out and backfires

Aug 3, 2016 10:01AM PDT

While running idles roughly bouncing between 500 and 1000 rpm. Runs good at 1500 rpm but rich. Backfires thru exhaust at 2000 rpm. Have replaced all sensors and pcm/ecm, timing gear set, distributor, fuel pump, oil sending unit, plugs, wires, distributor, you name it. Local Jeep shop has had on 2 different machines and it shows NOTHING wrong. Please someone HELP!!!
