The other day I was riding my 2009 Night Rod home and noticed it was running funny. At constant speeds it sounded like it was stuttering but when I gave it throttle, it was fine. About 10 miles later it through a check engine light and felt like it went into limp mode so I parked the bike and towed it home. After pulling the codes, I got codes P0108 and P1353.
Wanting to fix the P1353 code, I went to my Harley dealership and bought 2 new oem spark plugs to replaced the ngk’s I had in my bike and swapped the coils to see if the problem would jump to the other cylinder. Unfortunately this solved absolutely nothing and I’m getting the same codes and problem after clearing them and driving the bike around the block.
The only modifications done to the bike is a Vance and Hines exhaust paired with the fuelpak management system.
Does any one have any other suggestions on what I should be checking next? I’m stuck at this point and any suggestions would be greatly appreciated.
