Where's my MKII Cortina!! :-/

[muzbaz]

Back in the day you could swap out the points, brush off the plugs, tinker with the timing etc etc, nowadays The computer,, he say "NO" throws a light on the dash and you gotta limp home missing a nights money at least it allowed me home I guess?

I managed to get the faults read today and wondered if there is a technical guru that could advise me as to what problems I have.

The mechanic said The first one that mentions the injector drift could be a fuel filter/water issue and to change that first

Thank you in advance for any help/advice:
