#1

does anyone have problems with a vibration while car is in drive while sitting still. if so what was your solution.


#2

Check the motor & transmission mounts.


#3

Possibly exhaust system vibrating against floorboards or something else? I get this occasionally in the winter usually due to snow or slush building up against the exhaust.


#4

mechanic says no to that. he changed the rubber grommets on the mounts also but no change. car runs and drives great just vibrates while sitting in drive.


#5

Is this a new problem or a new to you car?

If none of the above and the vibration is a new thing, then the list would include misfire (usually would get worse with load but not always), or low idle which in your car should trigger a check engine light. Also, I will look into the mounts again.

I did have a 95 Galant and the mounts went out, the most annoying one was the transmission mount which was hidden somewhere under the car and was causing a lot of vibration.


#6

An idle speed too low will cause a vibration. An engine miss can do the same thing.

The most serious would be a cylinder (s) dropping compression due to miles and/or wear.

If the car were mine I’d run a dry and wet compression test to make sure I was on solid ground mechanically and that any repairs are worth proceeding with.

thanks will check that out. just bought the car so dont know how long . runs great. that is the only problem and its more of an annoyance than anything else.
