just replied to yours i think mine is not a fuel related problem tbh i think its a sensor but ford want £80 for the diag which may show up nothing??

just a touch unsure whether to get the diag done or try a new lambda sensor as with that unplugged mine idles fine but still hesitates a bit so that one COULD be the problem or maybe not

all the sensors are about £50 tho so alot of money to be spending on 5 or so sensors so dunno what to do

altho i shall be fitting the new fuel system as soon as i return from my hols whether that helps or not as it will certainly remove any further doubts i shall have
