Are you talking about the throttle body shaft seals? If so you will havve a massive boost leak.

Just did mine as well after finding out they were leaking when I did the boost leak test. Went with the OEM ones and an OEM gasket, costs was 12 bucks.

I didn't think so much boost could be lost from such a small seal, but damn, the difference it made was night and day. Luckily that was the only leak I was getting. Wasn't too hard to do, didn't even have to remove the strut tower brace (couldn't actually, car was in the air, didn't want the struts to drop out, ha).

Member aby@mil.spec also rebuilds the TBs. I got him to send me one, swapped it out, and sent my old one in as a core. I had lots of air coming from the shaft seals during a boost leak test and a very sticky gas pedal. All fixed now. Very happy.

Eventually the throttle shaft will stick. Mine got to the point where the throttle would stick and I would have to tap the gas pedal to free it.
