Car pulling left to right on acceleration on idle

[Barteur]

Hi All,

I was stopped on a red light yesterday and notice that with; Clutch pedal press down, transmission engaged in first gear. If I rev the car a little I feel a little bit of a shift from the car from left to right (torsion) just from winding RPM. What could that be (I was thinking maybe transmission or motor mounts) or is this normal?

I also noticed that with the Clutch pedal press down (all the way down) I can feel a vibration (maybe more a light picking) of the flywheel, no abrasion or friction but I still can feel something is this normal? Should I be worried about something or maybe this could be related?

I have never driven a car 14 years old so that might be only normal wear from time.

My Boxster is a 99 base with 75,000 km (40k+ miles)

Thanks for the feedback!
