My 08 Avenger 3.5L V6 just started "chugging" when in 5th or 6th gear, under load, at between 1700 and 2000 rpm. Above and below that it is smooth. In park, I hear somewhat of a knocking noise at about the same rpm range. The noise seems to be coming from the top middle of the engine. It otherwise seems to run fine. Any ideas?
have the same problem?
