[tex-par]

Hey guys noticed my SHO was out on the state inspection.... asked the girl friend to take it by the shop and get an inspection today.... it failed!!! YIKES it failed the NOX readings any ideas on things that would effect this number? I know these cars are particular at times and wonder if there are some things I should try.........One thing is I am not sure how well she got the car warmed up before getting there and I know that effects alot of cars and the numbers if they are not truely warmed up all the way.....

Helpful hints appreciated!!!!

Pull the spout plug next to the ECU plug in the rear of the engine compartment on the passenger side. Forces timing to be static at 10 degrees. It will make a dramatic decrease in NOX but will bring the HC higher.
