Good afternoon, These codes indicate you have an issue with misfire on cylinders 3 and 4. This is what we need to do .Check the spark plug condition. Replace as necessary. Check for voltage on pin 8, Yellow/Brown, at the ignition cassette. It should be about 10 V, key on engine off. Check for a Hz signal with the engine running, about 30 Hz at idle. Compare the signals with pin 9, Brown/Red, which is the combustion signal for cylinders 3 and 4. The codes are for combustion (misfire) detection circuits. Be sure to use the factory recommended spark plugs. Let me know if you have any questions, thanks. Charlie
