Has anyone had this problem? I have a 04 ultra with a v/h fuel pack and the settings are to specs.. The engine light will come on at different times then go out and back on again..I did code it and it threw 1353 code witch is no combusion on front cyl, but the bike is running great.I cleared the code and ran it out the road and it started to have the engine light come back on and off...What am I overlooking??? Thanks for the help in advance... I also changed the wires and installed new plugs...

make sure plugs and wires are stock...no screaming eagle, gold or platinum plugs. and if all is stock then its your fuel pack causing the false knock!!! putting a ride along fuel modifier such as a power commander or fuel pack can interfere with the harley knock sensor!

A loose injector will cause this as well as bad gas. You may also want to check the wiring connections at the injectors and the ECU connector.
