A few weeks ago I changed the oil like I've done many times, accidentally overfilled it. At the same time I changed the belt. 2007 Caliber SXT, started hard for a few days, realized the problem and drained oil & changed filter, now its making a whining noise during acceleration, I read that there were different engines in the later model 2007's, using a longer belt, could that be the problem? Or maybe a idler pulley
