when your injectors were serviced did you have the cold sart injector done as well? The cold start injector can leak. Have you opened up your AFM and moved the spring wheel? if you have moved it, move it back to sock. does the vehicle have any abnormal symptoms while driving?
Didn't have the cold start injector serviced. I didn't move the spring wheel in the AFM either. It has no abnormal symptoms while driving. I was surprised it failed emissions because the mileage hasn't been bad and its been running fine.
