my 04 speedmaster has 60,000 miles on it in the last 5k or so i have noticed a surge at low RPM granted it does need some long overdue TLC, has anyone else had a simliar roblem. I know fuel delivery can be a contributing factor but i was also wondering about if the T.P.S. wil give me any problems. i was also wondering if the balencers will throw it off?
