Re: engine stalling and hesitating after warmed up.
 

while none of the material I have for the jeep - including the service
manual - have any reference to a "Top Dead Center" sensor - I think
you're probably referring to the Crankshaft Position Sensor. They're
the same thing, right?

I got one on the way, in the mail. I'll let you all know if it fixes
it...

Re: engine stalling and hesitating after warmed up.
 

Hi Elijah:

Wow - this sounds a lot like my post... See my recent post:
"Help with 1989 Cherokee XJ LTD rough idle and acceleration"

My problem also started after the truck sat outside for about a month
without running.

I'm still trying to solve my problem.
