Hey tuners,
It seems like once one thing gets fixed i hit another problem but im coming up stumped and i'm in need of some advice. Well coming home from work wednesday afternoon my car ran fine in the morning to work but once i got off the freeway on my way home my car started to high rev at 2000 rpm then sometimes would go to 1500 then back up to 2000 and in some cases 2500rpm. first thing that had come to mind was a leak somewhere i couldn't find anything at all, then i pulled my codes and same usual ones except code 21*upstream ho2s stays at center* pop'd up but i have no idea if this would cause my idle to rev up and stay at a consistant 2k rpm any advice or someone that dealt with this dilemma could maybe point me in the right direction? thanks for your time and input in advance guys
its back under that hood i go and also some more research
high idle at warm up?
