Is it idleing too fast and dying when you put in gear, or idle too slow to keep running? Any codes showing with chk eng lite? May need to clean or replace IAC valve, spray down the inside of throttle body with FI cleaner. Past that, check the cave like he said.

Unplug the MAP sensor connector and look into it and see what color it is (red, green,blue,black, orange) Make sure you have the same one that was in it originally. Mine had orange, and NAPA, and all the GM dealers all said the black was the only one made now and it would work. It didnt on mine. Autozone had all the different ones. (Im talking about the black plastic sensor on the top right side of the engine attached to the intake, rectangle shaped with 1 connector and vacum lines) I always get those damn sensors mixed up)

My 85 V6 would stall going into DRIVE or REVERSE from PARK after a cold start. I added a new ground wire from battery to engine block ( a la $RICH$ ) and resolved the problem. Might be worth 5 min. to try it.
