Bad motormounts?
I have been feeling this rough idle vibration on my seat from time to time. Its not the low idle problem, it idles fine, it just idles rough sometimes when i first start it, I can feel it in the seat. Car has about 120K. GS4
Could it be bad motormounts? What are the sympthoms of bad mounts? Or is my baby gettign old and ragged

To check them have the car on and in drive hold the brake down push the gas and have someone watch the engine and see how much movement you get, and try the samething in reverse to. hope this helps.

That's good to hear. I recently had my motor mounts changed, but they didn't do the trans mount, and I was thinking of having it done. Assuming it's not a major job, maybe I'll have it taken care of at my next oil change.
