2003 Fuel injected Fatboy, TC88 balanced motor. It just started missing one day, two days later, it will barely run. Ive changed the fuel filter, fuel pump, fuel regulator, all the in tank fuel lines, throttle position sensor, crank position sensor, cleaned air filter, cleaned throttle body, new plugs, and still no love. Even removed and checked all electrical connections and ignition coil. Took it to an independent shop they had no luck either. They think the computer might have gone bad and i have corrupt maps. I havent looked at the injectors and think they may be sticking in either an open or closed state a little too long during pulse signals. Is that possible? The new plugs are soot black and the end of the exhaust is too (rich condition). Its going to the dealer tomorrow unless someone has any ideas.
