rite at the mo the revs are sitting st 200rpm and im sure its the idle control valve so thats an easy fix i hope and secondly the car started to slightly overheat when not moving but the temp comes straight back down when movin had some advice including a mechanic and dont think its the head gasket as there is no signs of that bein gone ie creamy under the oil filler cap and no bubbles on the dipstick and when a head gasket has gone pretty certain from what i have been told that it would over heat all the time even when driving so think its the water pump i think that is what i will do mat
