Any BMW experts out there? Just flunked smog with Hi HC and NO at 15mph. I was ok at 25. I have replaced a cracked duct between the AF sensor and throttle body. I think I am also going to change the plugs and oil (been awhile). I replaced the O2 sensor two years ago. Anything else i should be doing?

Being a 92', that should be a 2.5 M50 and as long as it isn't bone tired, should pass with a lot room to spare.
Start simple, just replace the plugs with good NP's or NGK's or Bosch coppers. If it's been 2+ years since your last O2, replace it. Then drive it, get it good and warm (up to operating temps), then go back in for a test. I bet it passes just fine. (IMG:style_emoticons/default/driving.gif) |
