When i acclerate it sounds as it's back firing and jerking a little bit. I took it to the exhaust shop and fixed the exhaust and it wasn't the problem. If you can help please tell before i **** all over this thing.

 

300 or 400?
have you done general maintenance to the car?
has it been doing this since you got it or recently after any change to the car?
