Can anyone give me a simple answer to to following: 1999 1.8 XEi. When I dip the clutch the revs do not drop back to idle speed, they remain at whatever level they were when the cluch was engaged, occassionaly they will begin to rise whilst the cluch is still engaged. This is an intermitent problem, but is becomming more regular. if I give the engine a hard rev it will normally clear the problem, but the driver in front at junctions does give a funny look in the mirror.
