DashingDaryl Posted September 15, 2004 Report Share Posted September 15, 2004 After cleaning up the Mouse Mess/EGR Problem I took my car in for an emisson retest. This time I failed for Excessive CO. Out of a 12 max for CO, I had a 12.72 and failed Hydrocarbons I passed at .28 out of .8 My NOX reading went from 2.42 to .83 and passed Any idea why this would be? I had a gut feeling I should unplug my battery to reset the timing, but I didn't have time to relearn the Idle, so I figured by the time I drove to the Emissions place, the car would have adapted. Was that a bad decision? Any Ideas? Link to comment Share on other sites More sharing options...
