Ive got an 04 standard softail, TC88 with V&H straightshots, and open K&N aircleaner, PCIII. Recently Ive been having troubles with it hicupping here and there, and sputtering randomly. Ive checked the aircleaner, plugs, and wires, and everything is great, but I cant get rid of this hiccup. Around mid winter last year, I went out to the garage to start it up and run some stabilizer through it, but my fuel pump made a grinding noise and the bike wouldnt start. When spring came around, the bike started up and ran fine until now. There was an error code that was triggered, so I went into the diagnostic module and cleared it, to see if it would return and nothing came back on. There hasnt been an error code since this happened like 6 months ago. I dont know if this would influence my current problem or not though. Any thoughts?
