1993 240sx ka24de auto trans. at full throttle it only revs a 2200rpm what going on my dad say that one cam jumped off timing. what wrong.or maybe it could be something not hooked up because i just changed the motor. can any body help ??????????????

i think the computer just went into limp mode, usually happens because the MAF is bad.

usually thats what happens when the car wont rev past 2500rpm

Sounds like buying a FSM for your model car would really help you out.
