Well it was time to smog the Viper, I took it to the Ontario Dodge dealer and it stayed there for three days. They said it almost passes. OK so what parts are on the car, is their next question. I have 2002 GTS, 17k miles, K&N air filters, Corsa Exhaust, Ramdom Tech SHF catalytic Converters installed 6months ago and AB plug wires. So I guess the question is: Any sugestions on how to get the car to run leaner.
