rev clock gone mad?

hi guys just tonight i noticed my car ticking over at 2000rpm when its normally at bot 1100rpm????

when im driving in gear it seems ok i think but when i push the clutch in while im moving the rev needle goes down to 1000rpm then goes to 1500rpm and back down to 1000rpm and back up to 1500rpm:confused: and it keeps on doin this as long as im on the clutch????

any idea guys??

yeah but is it a false reading or is the car actually reving high? if so then could be your idle control valve bud:freddy:
