Stumped with the wifes jeep

[robertjr]

Hey all,
I got a few problems I can put my thumb on so here i come begging for some advise. First when driving in like a parking lot at about 5-10mph the jeep will just die, It will start right back up and run okay can't explain it? another is sometimes usually after its ran for a while it will idle high only when its put in park or neutral yet again can't explain? And last but not least sometimes it won't start engine is not turning over can sometimes hear the starter motor spinning and other times nothing if you wait any where from a minute to 10mins. it will start have to leave the key on still unexplained? Thanks in advance for any ideas info just plain anything I would be very greatful!

Sounds like your Crank Position Sensor is bad.

First year and engine. The stalling could be the tps sensor or the AIC control sensor. Have you had therottle body cleaned? Do you mean the starter is working but it isn't turning the engine over? any extra info will be helpful. Dale

1989 4.0L no i have not had the TB cleaned and that right the starter will work but won't turn the engine over like that silinoid is out but only sometimes and other times you'll have nothing from the start at all. Hope that help, need anything else just let me know!

Maybe the ignition switch?
