01 Grand Am SE stalling

[david-b]

Hey all. I was on here before when I had bought a 2001 Grand Am SE 2.4 off one of my buddies non-running. Long story short, problem turned out to be a warped head.

Got that replaced with a rebuilt head and car runs. I have a couple problems still, but the biggest is that it stalls out on occasion. I can be driving no problem, and then I hit the gas (not even talking hard) the rpms drop to half 1/2 of what idle usually is and the motor starts shaking. If I hit the gas while it's doing it, the car will die. If I let off the gas, rpms go to idle. About half the time, I can hit the gas and it will do the same thing, the other half, will drive off normal.

It'll start back up fine, and actually run fine for a little bit. Also when I first start up the car (cold or warm) the motor seems to shake the car a little more than normal. But again, it's hit or miss... sometimes i does sometimes it doesn't.

CEL, SES, ABS, Traction, Secrurity... got quite a few lights on. I know the wires on the ABS on the passengerside are destroyed causing some of those lights to go on. Autozone is a little far to to try to get the car there so haven't tested that yet.

When I did the tear down, I replaced the O2 and CLT while in there. Brand new plugs. Also have tried a spare ICM (the whole cover piece as well) with the same results.

After driving around basically all day today, I learned that the car only starts stalling and bucking when it starts warming up, and then when fully warmed.

Any ideas at all?

Dosn't this car have a Air Mass Meter, or MAF sensor?
What ever!
I would try cleaning the Air Mass Meter, and IAT sensor with CRC MAF sensor cleaner.
