I failed on HC and CO the cat reading was fine. I failed the low and high speed test. Something was burning off the cat im guessing it was the wd40 and PB I used on the exhaust bolts and I sprayed a shit load on the bolts and some spray got on the cat. I also got code 21 when I left. Any idea how to fix this 1 day before tx2k8 please help guys.
