Post subject:  MIL FAULT CODE 4237

Wondering if anyone has had this fault code come up and what was done to fix it. When I look it up is says Long-term Fuel Trim – Bank 1. I called a dealer to get their take on it and they said it told them it was a misfire to do plugs, wires, cap and rotor.... but... the boat doesn’t have a cap and rotor... makes me question them a little. I plan to do plugs and wires and test coils. But would like to hear if anyone else has had this code pop up and what was done. Thanks!
