Hi again, today i have purchased some ngk iridium spark plugs, the correct part number is 4344. They cost me £10 each from my local motormania plus a little discount aswell.
Anyway i have fitted them and also used some copper grease and di-electric grease on the leads and WOW what a difference, smooth as silk now, the old plugs i removed were only 5 months old and were genuine ford plugs from my local ford dealer, they looked very good with no damage or fouling to any of the plugs.
I have gone down the route of trying the whole "its better to use FORD parts to fixed any ignition issues"
i have tried all of that to no avail long term, i just hope now that this will finally solve my acceleration issue and intermittant lack of power with a rough engine.
I would reccomend to anyone who is having similar issues and has tried all the changing of leads and coil packs, to give these plugs a shot.
