My mondeo idles at 1000 rpm when worm and will not go any lower. Is this a pass MOT wise ? I heard that if you disconnect the battery for a while and then reconnect it, the ECU or whatever, may sort itself out. Will this harm the memory of the car ? I have the radio code ready.
Could it be the thermalstat that is at fault because it never reaches the middle, only a third of the way even after a motorway spin.
Thank you in advance.
