I have the M113 engine and have noticed while sitting in the car with the transmission in park if I raise the engine rpm above 1500 rpm there is a noticeable roughness. Below 1500 rpm the engine runs smooth.
Any ideas what would cause this?

Engine mounts?

What Rodney said^^^^^^^^Do the tranny mount too....Very easy to check...

When the mounts went on my 500, the engine would literally lift the hood on stop and go traffic, when I came to a stop and felt loose when accelerating out ha ha.


You would feel it rock the car
