i went with what others were describing, symptoms were the same, very jerky, not just a tic of sputter,
i hooked my 16 into my scanner and watched all the tps pids and didn't see anything exact to pinpoint the issue.
i paid for the part myself, and did the install, vs trying to get a warranty repair, wasn't worth the long down time and potential aggravation
with your bike, is it all rpm, throttle ranges, or just at the tip in ?? mine trying to maintain say 30 would buck and jerk, if i recall. just a tic of throttle, past that was perfect.
