I have an 04 SLT with the V6. When the rpm's dip to 1500 or slighlty less and when in 3rd or 4th gear at those low rpm's the engine seems to stutter when you want to give it a bit of accelartion. I've heard the word "chatter" used before.

Dealer service mgr says he can sense it too but states there is no tsb for it. To me, this sounds mechanical vs. electrical.

Anyone with any thoughts on the matter? What to do?

Thanks for any help!
