Wondering if it's normal for the timing belt to resonate at certain rpms and vibrate/flop around?
New timing belt was recently installed along with all new OEM tensioner, tensioner pulley, idler, and balance shaft pulley. Belt tension has been gone over multiple times and re-adjusted to compensate for timing belt vibration/flop. Belt tension is within spec but a tad on the looser side (grenade pin inserts into the first hole on the body of the tensioner, into the hole of the push rod, but does not slide into the second hole on the body of the tensioner). Balance shafts are installed on the car.
I've never bothered to actually look at the timing belt while manually pulling on the throttle body butterfly valve when the car is running, but my coworker pointed out the timing belt bouncing around to me.
