What setting do y'all run? It seems when it's hot and humid in the 4500 to 5500 range mine runs a little fat. Mine is set a 0 currently. But 7 grand on up sounds a lots better. I think I may just leave it where it's set at but wondering what others run there setting on. My plugs have been in about 8 months and it have had a stumble or two after a little idling under a bridge. Once cleared out it runs fine. DDT shows a ign fault on number 5 & 6 and it figured it was them 2 cylinders loading up on fuel idling with it tuck in. Looked at plugs today. They looked a little rich not terrible thou.

Hey tom I would leave it at zero do you run no ethanol and what oil do you run if you think your coils are going bad swap them with 3and4 I have seen coils take a crap at idle but run fine on the big end

I'm going to -1. It fouled a set today. It's hotter than blue blazes down here in SC. Plugs were black.
