when i start my car it will idle up and down then the engine will shut off
i have a 94 delsol with a p28 ecu with a b18a block and a 95 gsr head with stock gsr intake manifold everything is hooked up when i had my b16 head on there it ran fine now it idles up and down i tried to adjust the big white screw under the throttle body but it wasnt loose is there anything else i should try thanks for any help

 

Sounds like the idle air control motor is either broken or disconnected. The idle air control motor on your engine is on the back of the intake manifold make sure it is plugged in. If you still can't get it fixed the down and dirty way if you don't want to spend a lot of money trying to figue this out just crack the throttle plate open a little.

 

tps maybe?

 

there is a tube thing under the throttle body. it's some sort of cold idle are thingy. the screw in side is probably loose. where there are two 8mm bolts and a plate take it off and use a screw drive to turn it back in. that should turn down the air going into the intake manifold. if you need help on where it is im me.
