Using your vin# XXXXX found 2 possible cause which are the exhaust system biding or hittin the underside of the car. Or the shifter cable from the floor or column shifter dronning. I have also found a few where the accelerator cable caused a concern. I suggest you raise the vehicle and attempt the concern in the air and inspect the exhaust. As for the shifter cable. Inspect the routing between the firewall and transmission. You may need to zip tie it in a better location. As for the accelerator cable concern. I solved quite a few of them by locating the cable just past the firewall and splittting a 6 inch piece of rubber hose and inserting a 3 OZ wheel weighta dn inclosing the cable also in the hose and zip tieing it on the cable. These are some ideas to try.
