I have a 06 SE 3.7L and the throttle response seems very slow (even compared to my 99 Malibu with 130K miles!!). What can i do to improve this?
First, if you gut the catalytic converters, the computer will start throwing fault codes. Second, I don't know of any place that "professionally" destroys converters since it would be against the law for a street driven car.You can however gut the catbacks. You can do it yourself, or professionally...
