Swapped the Idle air control valve off another 1.8 without fixing the prob. Dont know any Rover service in Hampshire. Any ideas?
Not sure if this applies to the 1.8 K series, but I remember on the 1.4 K series R8, there was a problem with the idle switch, which I believe was located on the throttle pedal assembly, and it caused exactly the problems you are experiencing. It is possible I guess that the switch is now on the throttle body, and so it may or may not be related to the plastic throttle body issue that has already been mentioned in a previous reply.
