I need longer studs for aftermarket wheel for 2000 s4 where do you get them? does anyone out there have some? Also needed are O2 sensors before cats?, I am having random misfires car seems to die out when I get on it???
Already checked coil packs, and checked for vacum leaks, not sure what pressure to pump up to, to check for turbo leaks, and regaped spark plugs to .024 from .035
