I just spend over $300 to fix my emissions because it failed, now it just failed again, but worse than before! WTF?! The $tealership replaced the EGR solenoid, cleaned out the EGR tube and hoses, adjusted my idle. I myself replaced the PCV and fuel filter and now Im getting higher readings than the first time I had it inspected. So whats next? I guess I should look at the condition of the plugs and wires, although I barely have 10k miles on them. Anybody think it would help if I put in some 91 or higher octane gas through it before I went back? Can anybody give me some suggestions on what to do next???? Thanks

Retard your timing. Waaay back. If it is advanced to 17 degrees this may be it. Is it failing for HC's? Thats a possibility. If it is failing NOx try bellding your cooling system and changing the thermostat seeing that you already did a EGR cleanout.

If all else fails just get a new cat.
