I spoke with the service manager this afternoon and he said their policy is to drive the test vehicle around the block or to let it idle for 3-4 minutes before subjecting the vehicle to the test. I've made arrangements to have it tested again tomorrow morning at 8:00am sharp. I go for a nice long drive and arrive just in time for the test. Hopefully that will be enough to get me by this time.


The service manager mentioned the problem may also be a faulty O2 sensor. The shop that installed my headers may have damaged it while removing it from the OEM exhaust.


In the worse case scenario, the cats may have deteriated significantly due to prolonged track use.
