There is a lot of rubber parts that deteriorate. The mentioned Motor Mounts, Transmission Mount and on the Drive Shaft has a Flex Disc on each end.

If you are having abnormal tire wear the upper or lower control Arms are mounted on rubber bushing that can rot out.


There is also a fuel tank vent that when covered with Mud and so on can restrict fuel delivery. With 1/2 Tank of Fuel drive without the fuel fill cap (the fill pipe now becomes the fuel tank vent) on and see if your acceleration improves.
