My 1999 Jeep Sahara will start just fine, but will sometimes surge during warmup. Then after it warms up, runs fine. However, sometimes, if I turn it off, then restart alittle later, it does not want to start. I know Im not supposed to pump it, but it seems to be the only way it will start. Then, it wont idle, and keeps dying. It will eventually run good if I keep it reved alittle.

have fuel pressure checked ...fuel pump maybe losing prime

SOURCE: 1991 Jeep Cherokee stalls, dies while running idling will restart

well i would check the tune up i have owned lots of jeeps and they needs tune ups about every 30,000 miles plugs wires cap rotor take a look at them and go from there

Sounds like the idle air control valve...buy a repair manuel and it will walk you through the steps to change it...it's not hard.

you check for miss how is compression

SOURCE: 1999 Jeep Grand Cherokee stalls immediately after

check intake manifold air temp sensor and engine coolant sensor...one may be out of range but not enough to turn on dash light. tests and specs can be found in chiltons or haynes, test is done with digital multi-meter.
