Everything else pass as in PCV valve, timing, etc. I had on a AEM CAI, and Skunk2 IM and a high flow cat. Going to put my stock air box back on and if i can find myself a stock cat. I failed miserably on the emission test, my HC and CO # was higher than average. I hope to get this shit done quick and soon cause i'm getting tired.....
The high flow cat is probably what is not working properly, they never do for long. Stock OBD2 is about 9 bills. You can get a factory re-man from an exhaust shop for about 3 bills and is authorized to be on your car. Since you already failed once, the tech. was obviously not too concerned w/your aftermarket cat. So even an non-authorized aftermarket cat might do you some good.
