You Have got it and hit the target

he as only done cylinder 1 and 4 which equals injectors 1 and 3

This is what i think is going wrong with most garages general. Over the last 6 months every scan tool seems to offer the injector coding function on ford TDCI.

every body and his dog as heard a story that they loose there coding and run poor.

I'm not tarnishing everyone with the same brush but most garages i have found just re-enter the codes in cylinder order not firing order and yes it clears the code and the light stops flashing.

but in fact the only one that has been correctly programmed is injector 1 / cylinder 1.

Then the car comes back a month or so later with the same fault???????? but this time another cylinder or maybe two cylinders.

Most at that stage bail out and out source the job , others change one injector or even all 4 and re-code then again in wrong order.

This is why they believe it's the tool at fault when then book it into the ford dealers and use IDS and the problem goes away.

This is not a pop or a dig at anyone on this post, its just what i come across and if it offends anybody , they some times the truth does hurt.
