2001 Galant w/6A13 SES - P0125, P1500, P300
I am new to this forum but have been a frequent user of the Swedish Mitsubishi Forum which is now defunct. My latest Galant a Station wagon model 2001 w/ a 6A13 engine (V6 - 2.5 Liter) is causing my same problems. Having made service on the engine new timing belt, new P/S+A/C and generator belts, spark plugs, changing oil, coolants. tensioners. The engine came up with some OBC-II errors P0125 and also P1500 and P300.
The P0125 saying that the coolant temperature is to low. A set of new thermostat and temp sensor was installed. It raised the engine temp a couple of degrees ( from 82 degC to 85 degC ).but the error came back.
The P1500 says that there is an error in the generator FR circuit. This error is not frequent but shows up not to frequent. Also the generator lamp flickers sometimes when driving.
The P300 saying that various cylinders misfires. Spark plug holes are cleaned and no oil in the spark plug holes.
I am out of ideas on what to do - please help.
