My nephew owns a 2002 Firebird Formula. He recently had a full exhaust installed on the car. MTI did the install and tune. Afterwards, you could smell the car was running rich. He got the car re-tuned and it ran better for a few days. But, then it reverted to running poorly, and the RPM'S surge when letting off the gas. They run up to like 1200 RPM'S. The car now runs worse han it did B4 the Full Exhaust Install. What could be wrong with the car? Fuel pump possibly?

take it back to the tuner, but it could be somthing wrong with the intake but if it wasnt doing it befor they messed with it I'd be pointing my finger at them.
