My cars sick. When I let off the gas or shift at a high rpm my exhaust sounds really congested. It sounds like it's backfiring a little bit and just all choppy. I know this explantion sucks but if anyones got any ideas I'd appreciate it.

Get your AFR's down to see if it's the problem.... Check your plugs as well. How many miles are on the car... what year, make?
