when you change from a 3.4 to a 3.2 should you change to a smaller belt.. I noticed when I got my car back from the dealer when I nailed it ( once ) it sputters kind of like a mis-fire... no ses light.. It tries to go but basically stalls a bit.. I dont think its my trans, But I do know it didnt do this with the 3.4... Any thoughts...Thanks guys..
