I dont know where this would go. It is not a suspension issue because it does the same thing on factory suspension or coilovers.

My friend thinks this has to be related to my power steering rack. Just to give you some info on my car. I had a massive PS leak and I decided since I was not going to put AC in the car I removed the compressor. I also removed the PS pump. I cut the lines leading to the rack and filled them with fluid then joined them.

Even before all of this the car was doing the same thing just not as back. I though maybe the pillow ***** were the issue. Nope.

Ok here it goes. Hope you can understand this. When I am driving lets say 40MPH and go into some boost ( lets call it 1-2 PSI ) and let go of the gas the car pulls to the right. No if I give it gas to 1-2 PSI of boost the car starts to pull to the right then goes left when i let off.

What can this be?

 

I was having similar issue, but only during braking my car would pull to the right. Don't know if you already checked your control arm bushings, but my front LCA bushing where bad there was more than 1/4" play. Anyways I replaced them and issue is gone.

Also check your engine mounts.

 

Yeah the control arms are in good shape. I am looking at pulling the motor to seal some leaks and I will check the motor mounts. I thought this would be a problem with the rear end, like the diff mounts or something.
