I am trying to fix the mother in laws Escort. It is an N reg, LX. Not sure what engine size. Gutless anyway.

It seems to have problems with the idle control valve. Horrible idling etc. Have removed it and cleaned it out with carb cleaner. Was already clean. AA had already cleaned it recently. Could it be the ICV is dead.

I am not a Ford man, so don't know what the regular problems are. Any tips from anyone??
