Hi,
I have a 92 929 that when I push the gas pulls to the right and when I let go of the gas it pulls to the left.

>?? Any ideas??

loose engine mount maybe?

rear sub frame might have a buggered bush. I would get that looked at soon ey.

check out my 929: http://www.cardomain.com/memberpage/591915/5

Your wheel alignment is probably off. The rear wheel alignment is adjustable on these cars, and there are alot of links back there...

I would definately get that looked at before you do much driving, it sounds kind of dangerous.
