I need a little help on a S-10 with 2.8 TBI motor. What I got is a 1990 S-10 that was a 4 cyl from factory.It caught fire then they put a 2.8 TBI motor in it. Then they pulled motor out. My son bought it and we put a 2.8 TBI motor in it. Got it running.What I need help with is the fast idle. Don't these things have a cold start sensor or something? It starts good cold, but when it warms up you have to pull the wires off of the throttle body so it will quit getting fuel, then it will start. This is just a woods truck. All I really want to do is get it where it will idle. And start back after it is warm. If there is a way to make it idle I'll put a swich in it so you can turn fuel off tot start this thing back. Like I said its a woods truck. It doesn't have to be perfect.
