well yes in a way...
the reason is the motor has a knock sensor (spark knock)and the rattle of the tension pully can cause the computer to retard the timing.. in theory that is ....
un plug the sensor it is on the drivers side of the motor by the center cyl..
sounds strange but what the heck wont cost anything to try this
