I have NGK Plugs in it gapped at 32..... I thought it was the oil seal in the VC causing the stuttering but I fixed that and it's still stuttering... right around 5000-5500... once I go past that it hits its powerband again and pulls like hell... I'm thinking about replacing all the plugs... and hopefully that'll fix it.... I'm trying the easy/small stuff first... Any other ideas? :help2: It's not the gas.. I'm running our premium (90 octane ) with quite a bit of torco which should equate out to about 95 octane.
Sounds like my old problems, but i fixed it wit new plugs and pre gapped plugs. Did you change the wires when you changed the plugs? If not try the wires? Heck, just do both and hopefully the problem goes away like mine.
