Uhm, just thought I'd update this post with my latest findings. There I was literally about to order a new wiring loom and brand new ETA see:

BUT, I also suffer with reoccurring distributor cap issues causing horrendous misfire and power loss after around 15 minutes. Normally last around 10 minutes then disappears. My normal resolution is to take the caps off and remove the tracking lines which go across contacts and give the contacts a clean up, which normally resolves the miss-firing for another few months. Yes I could change them and as they're 5 years old and probably need it now but cash is tight at the moment and they are 100GBP each.
However, this time I made a significant effort and scraped and removed ALL the corrosion off the copper contacts using a Stanley blade and wet and dry. Engine was perfect after...nothing new.
Now, what is new is that my reoccurring recent ASR light issue, guaranteed to light at 20 minutes use hasn't reared its head at all, even after the whole weekend of driving!?
YES, now that is interesting.
So I'm wondering if there is a misfire detection system that can also illuminate this light?
I was literally going to shift 1500GBP in replacing the ETA and Engine loom, and all I needed was a good distributor cap clean!
And the reason I've linked this update to this thread is that if I can recall correctly, I replaced the caps when I carried out the tie wrap mod... would seem to suggest misfire recognition?
Any thoughts?
