Alright sorry that this question is not about a Grand Am. But I drive a 1991 Chevy Corsica with the 3 speed auto and the 3.1 v6. Well the problem is when I have my foot on the brake and the car is completly stopped and in the drive gear it starts shaking. Well when i am stopped and i put it in neutral or parkl it will not shake it has been doing this for a while I thought it might need a new fuel pump that was not it and it has had a tune up so does anybosy have any clue what is going on with it?

88 corsica with the 2.8 v6 was my first car and it did this same thing when i was stopped at lights. It was a pile so i didnt care but my first guess would be to check the motor mounts

I had a '90 Beretta GT with the 3.1 V6, which is basically the same car, and it did the same thing. All my motor mounts were fine and the car ran great, it just seemed like the idle was to low when I was stoped in gear. Never tried to raise the idle, no real bad problems arised from it, other than dim headlights while I was stopped.

Check all the lines for vaccum leaks. You can try raising your idle, but if it isn't a vacuum leak it may be the converter. That would also explain it smoothing out while in N or P.

Yeah, I meant to add that it might be a bad torque convertor, I had mine checked and it was ok.

I agree with the vaccuum idea. Check for leaks. That's usually a common problem found when you have a rough idle while stopped in gear.
