Once my 2000 Cherokee warms up, it hesitates and the tachometer flutters upon acceleration. It is a 4.0, automatic, 4x4. Tried 02 sensors and TPS, and it did nothing, even replaced coil pack and crank sensor. Any ideas?

Check engine light or codes?

No engine light, no codes.

I think then that it is probably fuel related. Perhaps you are not getting enough fuel to the injectors. It is a pain to work on the pump or regulator in yours since you have to drop the tank.

I'll put a pressure gauge on and try.
