I got a chilten with microscopic pic's and a fellow said I would need a pully puller, I think I can handle it with a lil direction. How bout it fellow Jeepers, a brotha could use some help, its our only car right now. 99 Jeep Grand Cherokee Limited 4.7L
The 5.9 in my TJ did this, sometimes it would miss for a bit, sometimes stall. ALways just after warm-up, 8-10 minutes of run time. Crank Sensor fixed it.

I too have gone through this and now am going through it again 2 yrs later. I have an 05 wrangler X 6 spd, 4.0L. After replacing both sensors ( crank/ cam), as well as gear on distributer. I had ECM reflashed at the dealer, about $100.00. No problems until now. Engine would occasionally stumble at idle, then popped a p0016 code. Replaced both sensors again, erased codes and all seemed fine and ckps code popped up. Will try fixes on here to see if it helps

When my crank sensor went it WOULDNT buck or hesitate. It would just turn off, like someone turned off the key. It did the same on 2 different vehicles.
So the bucking, hesitation and almost stalling but still running makes me think something else is the problem.

Also those sensors can be bad right out of the box. I put a brand new mopar crank sensor in and it went bad in a few days.

Good luck
