Without a picture or smell-o-vision I can't say for sure. Do you have an aftermarket intake installed? If you do try disconnecting your battery and pump the brake pedal 3 or 4 times turn light column on off to discharge the computer. When you reconnect, take it out for a drive, accelerate pretty quick, a couple of times and drive at 45-65 for 10 mins. See if the computer can learn new Air/Fuel ratios with the less backpressure.
I support the military, fiscal responsibility, Hemp, legalization of Marijuana over 21, smaller government and the Bill of Rights.
NSA: The only part of the government that actually listens.
