poor performance

[92nismo]

i have just recently bought a 92 240sx se, it runs fine drives and everything, but in teh mornings i have to let it run for about 15 min for it to run correctly, it feels like a lot of power is going somewhere, just not to the ground. and also seems to missing when i get on it, kind of like a sputter noise. im going to get some new spark plugs and wires tomorrow so i hope that will take care of some of it. i know it has alot of more potential then its giving me what can i doo.

that sounds exactly like my problem.

Everyone has told me to replace the coolant temp. sensor and to check the codes.

so u mean that it's ok after it warms up to operating temp?

check codes 1st to see if that cts or any other sensor is "read by the ecu"...

i do believe its the cps Crank position sensor, havent checked the ecu yet my cars at the paint shop but im pretty sure thats what it is, oh yeah where is this located at if it is the prob.
