My aunt has a 98 cherokee with 4.0 I6. She claims it dies out on the highway and sometimes at idle but only when the engine is hot. I had the car for a whole day and was only able to get it to stall twice in the garage and thats it so i see no pattern. Ialso tested the fuel pressure on a long test drive and saw no issues.

I suspected the hall effect switch so i switched that out as well as replaced the over do plugs,wires,cap and rotor and the problem went away.

Oh and it threw two codes...
1. Primary ignition circuit
2. Crank sensor signal

I cleared the codes and did the tune up and neither codes came back after running the jeep for quite awhile.
I just gotta call today that its stalling again!
Any Ideas?!?!

Im in a real pinch hear thanks
