ok, well, i changed the fuel lines(all of em) 1 which was leaking gasoline, and i cleaned the carb with some cleaner while running. Still at about 3000-3500 rpm in any gear, it feels kinds rocky. i havent changed the Blue Coil, because the consensus seemed to be a fuel problem. Could the carb be out of tune? today at work it was "deisling" and 1 time it backfired.
