Hello,
Flunked inspection here in NJ for Idle emissions, I think this may be something new as last years paper didn't have idle emissions. Anyway here's the readings,
Idle - Fail
HC ppm 304 (the standard is 220)
CO% 2.25 (the standard is 1.20)
High Idle passed at 39 for HC's and .07 for CO
What confuses me is that no codes (OBD1) which I understand has a lot less sensors the the OBD2. What do you do to reduce Idle emissions. I guess I'm a little spoiled with the OBD2 system which red flags everything and to me is easier to fix. This is a 93 ODB1 and don't know where to start??? I would take it somewhere if that's what I need to do. Any suggestions please would be appreciated. I rarely take the car anywhere to be worked on but I do have a corvette shop near by that has a good rep. Thanks
