I just picked up a 2004 FLHT about 2 months ago. I've had a problem with eratic idle and it stalls out. It will allow me to restart it right away. I have checked for codes but there is none. After I ride it for a while it seems to misfire. It backfires through the carburetor. I've had it stall out on me while on the freeway doing 70 MPH. Before I could pull over I throttled it back to life. I have changed the plugs and wires. Seems to be running hot, then acts up on me. I would think it's the coil but it starts right back up. I need some help with this. I have been reading for a while and decided to join. This place is very informative... Please help!!!!
