My Ford Fiesta Zetec is now miss-firing particularly when I am just idling
along and decide to accelerate quickly.
This has been going on for some months now as I have since changed the spark
plugs, distribution leads and had the engine cleaned out just in case the
cause was contaminated fuel. Unfortunately these changes have had no affect
what so ever and left me none the wiser I hasten to add.
Can anyone out there offer any advice?
