reason I ask is because when I start my car it used to revv to 1500 and slowly come down as it warmed up. Now when I start the car it kind of violently revvs to 2k and when I let my foot off the clutch it comes back down to 1.5k. there isint any loud noises I can hear , i do feel a slight vibration if I put the pedal in half way but depressed 100% or pressed 100% I dont feel or hear anything weird....just something I noticed my car was doing and I am curious.

 

nobody?
