tohatsu m50d2 idle issue

[tom_20000]

Afternoon all, any Tohatsu experts out there? I have an unsteady idle, and almost a miss I think. Fuel doesn't seem to be an issue, and I read about faulty coils. As they were Cheap picked the boat up from storage today and changed them over and whilst it doesn't appear quite as pronounced its still there. Also when removing the plugs whilst idling cylinder 1 & 2 impact the idle, but cylinder 3 doesn't do anything. I've moved coils around, does anyone have any ideas before I tie the boat back? Hopefully not a new CD unit video link attached

Thanks in advance

Could can be a pain on these.

When you swapped the coils did the effect follow them?

Coils not could lol

Yes, it's marginally better I think. Id swap back but damaged a plug boot trying to swap them. I've swapped for naraku coils that someone recommended. It does it straight from start up. Idle screw is 2.5 out also on number 3. Changing that didn't make a difference

The nakuru coils are more reliable but just make sure the earths are good, go overboard on them. Put silicone grease or similar on them to stop corrosion. I ran Nakuru coils but with NGK red boots on mine, more waterproof

I've looped all the earth's so all "should" be ok there. Need to greese them up though, thanks for that
