Yesterday when I went to go test drive a 91 FC, while inspecting the car, I noticed that while the car was ideling the engine did two things, one I shock prety bad. Are the motor mounts gone? Also it sounded like the car was back firing, but it wasnt as lound as a back fire, im not sure what it was. I thought it might be the ideal, but the car was idelin fine, wasnt bouncing up and down at all. One more thing while the car was ideling, like at a stop light or somethin, the shift *** shock pretty bad.
Is any of this normal or whats goin on??

-Thanks
P.S. Does any one know any good mechanics in northern VA.

 

That "pop" you heard while it was idling is fairly normal to a rotary car..

The car MAY have a vaccume leak that would cause the engine to idle rough and shake..

The engine mounts probably should be replaced anyway.. but it isn't a big deal and they only cost about 30 bucks a piece.

The shift **** shake will die down when the engine shake is taken care of; BUT replacing the shifter bushings (really easy and cheap) takes the slop right out of the shifter.

 

popping at idle is normal. Shaking and vibrations in the shifter are also normal. New motor mounts and you're ready to go.
