Hi,
Is it possible for you to record the sound and upload it for me to hear? As far as the misfire, it could be a couple of things. Code 42 is related to the electronic spark timing. If it is off, that is what is likely causing what you hear. I attached the diagnostics below from my manual specific to this code.
Code 45 does indicate a rich fuel mixture. It could be related to the regulator. The pressure regulator is a diaphragm-operated relief valve with system-operating pressure on one side and atmospheric pressure on the other side. The function of the regulator is to maintain a constant pressure to the injectors at all times, by controlling the flow in the return line by means of a calibrated bypass.
Note: The pressure regulator on this unit is serviced as part of the fuel meter cover and should not be disassembled. If you look at the last pic below, I highlighted the regulator.
Let me know what you find.
Joe
