Troubleshooting an Engine that Stalls at Idle When Warm ...

Replace the temperature sending unit/sensor. This sensor tells the computer to put the engine into cold start mode and it then sets idle a bit higher and puts a bit more fuel into the engine to keep it running without having to touch the throttle. Once it's warm, sensor tells computer to go to normal run mode and it's done. No problem.

You should try looking at the transmission fluide, it must be short. If it is, you should go buy a transmission fluid. And make sure you car pipes has no leak.

I had a similar problem with a Ford Excursion, it turned out to be intake manifold gaskets. It would stall then start right up again, it ran fine during warm up. But, once fully warmed up it would stall at stop lights and stuff like that. I did get a check engine light, the code was lean condition. I don't know on a Jeep, sorry I can't be of more help.

hi, this problem to me sounds like the oxygen sensor needs replacing as when the vehicle is first started or from cold you will find it starts with no problems but once its up to temperature then you start getting problems.
This is due to the oxygen sensor(lambda sensor as its proper name) not working when the engine is cold it only starts working when the engine is up to temp so if this is when your getting the problems then this is what i would look at first.

Let me know how you get on or if you need further assistance ok

Sounds like fuel filter.

Check throttle position sensor, and IAC motor. Possible the intake is needing to be cleaned also.

You need to check components again when the engine is hot and in no-start condition, otherwise, you will get bad info...obviously whichever part is doing this works fine cold. ones that react most to heat are crank pickup, ignition coil and the fuel pump.(bad ones get hot and bind up)

tps sencor or maf sencor

get a couple bottles of gas line antifreeze .. if you don't already use it and add it to the gas.
