my motor has developed a something weird. at WOT, right when it gets maxed out, it is cutting back just a hair. Its almost like the butterflies are opening all the way, then actually opening passed 90 degrees, and restricting air flow. I know this isnt happening, but thats what it feels like. Not cutting back much, maybe 100-200 rpms. I messed with the idle jets the other day but wasnt sure if they affected WOT. ideas?
