this only happens when i first turn the car on after its been off overnight... I turn the car on...have the clutch held in.. and car starts and the revs go up to 2k ( while im only holing in the clutch) once i let off the clutch it goes back down.. but this never happens when i turn my car on after i drove it durring the day. is this a way of something getting heated up? i mean i don't hold the clutch in forever... just to get the car started.... my first stick car so am i missing something?? is this normal? why does it do it?
