Question about 2000 Jeep Grand Cherokee
Your only problem friend, is the temperature sending unit/sensor. Upon cold start, this sensor wil tell the computer to go into cold start mode putting a bit more fuel in and raising the idle a bit to keep it running when cold without using the throttle. Replace that sensor and your good to go. Makes sense, right?

SOURCE: Stalls when engne warms up
Your ECT (Engine Coolant Temp) sensor is bad. What's happening is at cold start it richens up the fuel mixture and as it warms up the ECM thinks it's still cold and essentially the "choke" is still on. Also check your coolant level. If you don't have enough coolant in you engine/radiator, the ECT doesn't know what to do so it thinks it's cold.

Man you have a lot of things to check out. You really need to start out by getting a computer scan done on your truck. Diesels are not what they use to be, and there are to many things to look at. My initial thoughts are that you have a bad injector, but if you are not mechanicaly skilled this is not a job for you. Please save your self the head ache and get the scan done by a reputable dealer or mechanic not the cheapo parts store. It could be anything from a dirty filter or line to a injector.
If you get the scan done and then its something you can do your self, go for it. I have told my friends if they want to buy a diesel, which I am not against at all. If they want me to work on them they have to buy the scanning tool for it because finding the problem takes for ever.
Once you get the scan done then let me know and I can help you more.
