alrighty now...i got sum problemos...does anybody no wats wrong here...now when i start my car it starts up fine but shuts off after like 5 seconds so i crank it again and starts up and stays on(it does this alot everytime now).now after i cranked it for the second time and stays on,everytime i shift the car into drive or reverse,the car stalls.the way i prevent the car from stalling after i shift it is i press the gas while in park and then shift it while it revs down...but when i stop at a stop light it stalls unless i keep my foot slightly on the gas to keep the engine reving while my foots on the brake and its good.and when i drive it and then when i put it in park and leave it running it stalls also....my car loves to stall...now about a couple of months ago my car shut down on me while i was driving so i replaced the ignition module,spark plugs,wires,rotor button and got it 2 run again but just hasnt been the same...new battery also.

 

also i was told 2 change my IAC but i got like 5 from the junkyard and tried them all and didnt help one bit.

 

Snag a couple of MAP sensors from your fav junkyard and see what happens... It's either that, or the vac line to it is broken or clogged, or you have a vacuum leak elsewhere.
