Smog Help 06 WRx (CA)
Hello help would be greatly appreciated.
Just tried to Smog my 06 wrx, uninstalled my accessport back to stock right before going to shop, from stage 1. It failed obd systems check and CO% at 2500rpm
Ive heard you need to drive around 50 miles before taking it in to pass obd test is this true?
Would it be beneficial to tune to economy mode drive over 50 miles then take it in? To help with co%
Only has catback exhaust on it. Have had problems with secondary air flow valve in the past is this a huge factor?
