Boost Leak Test

[DSM_JAY]

OK so I boost leak tested my car at about 12-14 psi and leaks at the biss o-ring, one vacuum port, one from behind the TPS and another port on the manifold. The vacuum port on the throttle body and the one on the manifold im not so worried about. do I rebuild my throttlebody or di i buy a reman. My car undriveable and getting sick of this. surges from 1500-2200 rpms warms up and then stays at about 1500. running richer than hell. replaced every sensor i found that was bad. I NEED HELP................ thanks Jay

just replace the o-rings, and it should be fine. new tb gasket won't hurt either, like 2$ or less.

Replace the throttle body shaft seals and the BISS o-ring. Did you also check to see if you are leaking at your injector seals?

forgot to include that yes I did, i used soapy water everywhere and saw nothing at the injector seals.
