Stalling of the jeep while at idle or in motion.

Asked by Thomas Nov 27, 2018 at 11:40 AM about the 1996 Jeep Grand Cherokee

Question type: Maintenance & Repair

I have an 1996 Jeep Grand Cherokee with inline 6, 4x. It starts and will run
for a bit then it stalls out while at idle or driving. It will fire back up shortly
after (if not flooded). could it be the crankshaft positioning sensor, throttle
body sensor, intake MAF sensor, Coil (maybe), injector or rail problems (no
leaks)? I have already replaced the Fuel filter twice, fuel pump, plugs and
wires, distributor cap and rotor, mapping chip, Radiator (diff problem, but fine
now). I am at a loss currently and about to plug the damn thing with a few
.50 cal rounds. suggestions?

You should scan for fault codes and repair accordingly. A common failure on this engine is the crankshaft position sensor, code P0320. It will cut out your spark, the tachometer will drop suddenly, and then it will run fine until it does it again. You've done a lot of improvements on this Jeep so don't give up yet. It will be something simple. Tell us what you find.
