That's some shoppin list. I don't see mention of new ignition leads.
Since ewe have individual coil system, can ewe swap them over to see if problem swaps cyls?
Do you know which cyl cuts?
Do plugs look the same colour? Are they standard?
Plungers could be a clue.
Whereabouts are you to? Someone local may be able to offer a fresh pair of eyes!! I admire your persistence.
I have yet to repeat the spark test. In my haste I put the plugs back in after finding that one was bad and didn't look to check the spark quality of the new ones. Idiot. I was so sure I had finally found the last fault. Ho ho. New coils / leads / caps / plugs all fitted. All resistance checks good. I will run the spark test again some time next week for sure. Previous test showed bad sparks swapped sides when swapping plugs over so bad plug for sure. As it has had a decent run since fitting new plugs the colour check will be next. Just need more time! Thank you for your input.
