My first guess is a bad O2 sensor. Unplug it and see if it runs ok.

Seams sorta like a sensor problem, does it do it in neutral? Maybe bad/dirty IAC? Might be the transmission, idk a thing about these transmissions except how to change the fluid. Is the tranny new or used?

The tranny is used that came out of a jeep that the frame snapped on so it was good and the o2 sensor wasn't it what do u think about the coolant temp sensor being bad
