Hi

Re 98 Camaro, LS1, A4:
-Mac headers
-Mac cat Y pipe
-K&N induction
-Borla cat back
-MSD Coils
-46,000 miles - compression is good

Plugs, wires, air filter, front 02s, cats and fuel filter are all recent. Faild on Hydro Carbons both idle and driving tests. So much for my high energy, multi-spark ignition. See the attached reports.

There are no tuners in my area. Before I go to great lengths to get a VE/PE tune I want to check all possible ignition, fuel, emmission system diagostics.

Any help appreciated.

Thanks JA
