revving when push in clutch
 

I was wondering if anybody has ever had or heard of the problem when i am driving and i go to shift when i push in the clutch the car will rev up about another 500 rpms and slowly rev down. It mainly happens when the car is cold but it still sometimes will do it after it warms up. If when it starts revving up and i snap the throttle real quick it will idle back down normal. Any suggestions???

How high are you revving it? When the car is cold the idle is pumped up and if you shift before engine idle speed it will try to jump up to the higher rpm.

when its cold i drive normal and i shift at about 2600 rpms and it will usually jump up about 400 rpms
