Nick My garage have tried most of the 'quick fixes' for my idle problems, it looks like the ECU is to blame. I would like to take you up on your offer of repair services, if you could e-mail me off-list with your address and a price for the component/delivery I will send you a cheque for the bits. If you could also advise on your charge for the repair and timescales that would be great. As an aside could it be that this circuit is also responsible for the car's battery drain?
