It's all over the place, nothing is consistent. It will cold start miss one day, it will run perfectly until it warms up the next, and the first few days it went away with fuel system cleaner. I think it's getting progressively more common but less annoying. I think it used to sputter up to 6k, now it seems to go away after 2 or 3k. Annoying for traffic but pretty OK around town.Haven't read the thread; skimmed parts of of the first page. But that and you were saying it cold-started missing, sounds like my experiences with failing spark plug coils. See my comments on testing coils here... 2005 r6
Okay I see the bike is modified. When troubleshooting, the general idea is to set things back into parameter... which often means stock. But if other things are modified, such as the exhaust, the PCIII may have been added to compensate; in which case it's best to leave it be; unless you have the original parts.
The issue I'm worried about now is the cold cylinder. I switched the coils with 1 and 2 and it did nothing. I pulled the harness out (broke the clip on my cam sensor...fak!) and all the wires LOOKED fine. I don't know if there's a plug up stream where I could take it off the bike and continuity test them all?
