High pitch vibration, engine related, what is it?
2003 base 996 coupe, IMS done 2k ago.
There's a very high frequency vibration in the steering wheel that is definitely from the engine. (varies with engine rpm)
It's ever so slight, but enough to make my hands feel like they've gone to sleep and are coming back to life after 30 mins or so.
Do you'all experience this? Any ideas on the cause?

stopped and in neutral the vibration can still be felt, varies with engine RPM. I have a Tiptronic four brand-new michelins, verified that all rims are straight and balanced. Could be wheel bearings Maybe?

Motor and tranny mounts failing will give a different vibe in the car...

Check your power steering fluid level. Move the steering wheel in/out and see if that makes a difference. As said, most vibrations from the engine/transmission are transmitted to the car from worn out mounts (engine or transmission).

What about low-speed vibration when engine not warmed up; goes away after 10 min. driving and not felt in steering. Previously diagnosed with cracked ignition coils and possible misfires. /X3

Three Wheelin'
Was the flywheel replaced along with the IMSB? I used to have a 95 mustang GT. I did a clutch and flywheel and got a bad, unbalanced flywheel. Had a pretty bad vibration through the stick and steering wheel.
