e240 1998 auto.at around 1200 and 2000 rpm i have developed a vibration through the car.it felt like prop uj or bearing vibration but you dont have to be moving.ive checked the engine and box mounts and its running smoothly so i assume its fireing on all (12) plugs.ive code read it and its clear.any ideas?
I would clean the AFM meter... use the AFM cleaner.
There was an issue in these cars about the harmonic balancer deteriorating. I seem to recall that the engine would vibrate some time before it broke up. By then, it was a costly repair.
However, just checking it was simple enough and inexpensive. You say the engine runs smoothly so this does not seem to be the cause, but I would check, just in case.
