I have a vibration problem that is driving me nuts.
It is coming from somewear on or in the engine.It starts at 2200 RPM and is at its worst at 2400 RPM and is gone by 2600 RPM.It seems to be most noticeable in 4th gear,but you can feel it in netural at those RPMS.The reason it is really bugging me is those are my cruising RPMS in 4th and 5th gear.I changed motor mounts and made sure nothing is touching anything. Anybody have any ideas.

Thanks Rod

I noticed it all last year,but it seems to come and go.Sometimes you can really feel it and other times hardly at all.With the car siting still in netural and takeing the RPMS up to 2400 you can feel it through the whole car.Even by touching the bumper.I am starting to think its in the exhaust,even though its not touching anything.Any ideas.
Thanks Rod

Is the engine shaking or just the car vibrating? could be loose flexplate bolts.
