My son's '95 Camero has started to shutter/shake when he accelerates. When he lets off of the gas and/or slows down the shaking stops. We recently had new tires installed so we took it back to the garage to make sure that we had not thrown a weight or that a rim might have been loose or bent. He also checked the transmission fluid level and it was at the proper level.
Any suggestions?
Thank you in advance!
