I have a 2006 camry 4 cyl with @140 k.... Runs and drives great.

I’m noticing a slight medium frequency buzz which seems to come and go..... It can be felt through the accelerator pedal. It is very mild, but id like to figure out whats causing it.

It seems to happen while not under load at speeds about 45 or so... And shifting into neutral has no effect on it’s frequency or intensity.

Im thinking it may be an engine mount. Any ideas?

 

Any seat vibration?
