So I started developing a problem at the end of the season this year. In second gear mostly (but sometimes other gears I think) under WOT I will get a momentary hesitation in the high rpm’s (11k-13k). My shift light will flash with the hesitation but I don’t think it’s clutch slip as I stay on the throttle the whole time. Any ideas? Newish plugs and I don’t have a power commander any more. Happened through multiple tanks of gas.
