Danny, before you 'replace it' check to make sure that the switch is defective. It may be that the throttle plate cam has worn such that there is not enough throw to actuate the switch. Probably a disassemble and inspect. These crazy electro mechanical devices can fail the electrical test sometimes due to a mechanical fault good luck KeithG "danny" <> wrote in message > Hi all, > > A friend was looking over the car today, both of us trying to find out > why my fuel consumption is high (computer says an average of 20 imperial > MPG) with a mix of motorway and town driving.
