i just put a new used motor with 60,000 miles in my 1993 240sx it's a ka24de and i it's a auto trans. at full throttle it's only revs to about 2200 rpm, what the deal. my dad ws saying that he is pretty sure that one cam jumped off timming. could that be it. well because my timing mark the crank shaft pully dont line up to the ones on the engine when the #1 pistons is up on compression. well i hope some one can help or i have to take the motor back on warranty.

do your basic diagnosis first, check the ECU for codes, make sure the maf, cas are all within spec, ect...

what do you mean "it die right down" it stalls while your foots still on the gas or when you let off it dies?

I'm sorry, but I had to laugh out loud when I read your signature, racing_240SX.

I think what you ment to say was "Driving a Honda is like winning the special Olympics - Even if you win, you're still retarded"
