ok, most of the time it idles fine (IMO anyway!) but once shes warmed up, on the odd occassion when the air conditioning is on and i am stationary the revs will drop to 600/700 rpm. turning the airconditioning on and off does alter the revs but they drop down again.
also, if the car is idling and you give it some gas, the revs drop for a split second before going up.
help!!
