The car has no cats, its an offroad y pipe. I can check the plugs and sensors, but its been running bad for about a week now (really rich with the symptoms above) and only until today did it throw a code. I know code 65 is right o2 sensor rich exhaust indicated. So I guess it could be a bad sensor as well.
I'll check the sensor and spark plugs, but I am curious as to why it would run so rich.
