i used a p72 ecu, i wired the knock sensor,vtec and oil presure to the ecu, i have 2 sensors that arent hooked up, the sensor that sits on the top of the intake manifold (has 2 vaccum ports from it) and the crank sensor is not hooked up, i was wondering if this could be the probelm, i always used chipped ecu's to elimante the crank, and does anyone have a link to where i can find the 0bd1 pinouts on a p72, car starts up fine and idles but sputters when u give it hard gas so i know the problem lies in withing them 2 sensors

 

(i always used chipped ecu's to elimante the crank) i meant knock

 

Why aren't the sensors hooked up? you need to plug those sensors in and then your problem will go away. I believe the sensor on the top of the throttle body is your map sensor, and crank angle is probably causing your sputtering problem because when my crank angle went bad, I had the same problem.

The one on top of the manifold is the EVAP Purge which really isn't necessary to hook up, only if you are worried about emissions. By crank sensor, if you are referring to the crank fluc. sensor by the alternator then that also doesn't need hooked up since you are using and OBD1 ECU. Are you throwing any codes?

 

im gonna see what the code is? does anyone know a site where i can get the ecu codes? thanks guys ill see what it throws
