i went through emissions today and i failed the hydrocarbons (standard is 2.00 and i got 2.48) and i almost failed the NOX (standard is 3.7 and i got 3.3 "the guy said it was creeping up really fast") I then took my car to my friends muffler shop and they took my exhaust temp and with the stock, four cat pipe I was over 550 degrees in front of the front cat and behind too! It maxed out his digital temp gauge i was running so hot! Ok now my question is, could it be that my cats are shot? I just swappws my stock pipe in within the last week and it rattled and you could hear things moving around in the cats. Im running 14 degrees advanced timing, 30 pounds vacuum on with 24 pound injectors and a stock cam. My entire combo is emissions legal too? Could it be my cats?
thanks for any help,
Drew
p.s. my engine isnt overheating either, it stays about 180 ish
