so i finished my swap(or so i thought), its an obd2 b18b an i converted it to obd1 with wire harness an injectors an dizzy an ecu, prob is when i start it i have to give it gas an keep gassin it for it to stay on, on obd2 ls's theres a sensor on top of intake manifold, i have not wired it up yet cuz i jus got the plug to plug into manifold tonite, could this be the prob? jus wonderin on opinions, i will have results tomorow mornin when i wire it up

 

when you give it gas, does it hesitate, or is it smooth? The sensor on top of the intake, is it on the TB? if it's the MAP sensor on the TB, that could be it. Wire it up and let us know.

 

Have you tried adjusting the idler screw on the TB?

Brian

 

yes i adjusted the idle screw, it is the sensor on top of the intake manifold, only comes on obd2 motors i think, its gonna get wired up today, we ll see if thats the prob or not

 

As far as a plug on top of the manifold which one are you talking about, IE what does it look like? TPS? MAP?

Brian

 

its on top of the intake manifold on the throttle body side of the manifold, it has one plug an one spot for a vacuum line, i will try to get pix up, also, i have a pr4 ecu, not sure if its obd1 or 0, will this matter at all?
