I bought a 91 Camaro a couple weeks ago for a project. Overall the car is in great shape. The big problem is when I start the car and leave it idle or when I come to a stopsign or light. It will stall on me. But when i keep giving it a little gas at a stop it will stay running. I have check the throttle body. Got it scanned. Changed plugs, wires, dist. cap, and rotor. I have also check for vacuum leak. I unpluged the MAP Sensor last night and started the car up with it unpluged. It keep an idle but sound like it had a miss in it. and when i plugged the MAP back in the car died. Please help me and give me any info you might know. Thanks
