I just put a turbo back exhaust from Road Race Engineering on my girlfriends 99 GST. Everything went together great and it sounds pretty good.
Problem is...now when driving and slowing/downshifting to come to a stop the RPM drops down really low(<400) and will then go up to about 600 but occasionally it will stall out instead of going back to the normal idle. It re-starts immediately when it does stall out though. I checked to make sure all vac. lines were connected, checked brake booster vac line, & cleaned out the MAS plug. None of that helped at all.
Everything else seems fine. Nothing really abnormal. Its just kind of wierd that it happened right after I installed the exhaust. Anyone have any good ideas.
BTW...the only mods are 3" turbo back exhaust w/high flow cat, and Apexi intake.
