The car has been throwing the p0300 cel which is random engine mifire and has been bogging down big time and hard to accelerate with a bad idle. It will drive fine for about ten or so miles then start doing this. The air/fuel meter is stuck on lean at any rpm and will not cycle like normal. The spark plugs have been gapped at .028 and it has new wires. The 02 sensor is a bosch sensor that was replaced about 3 years ago. Does anyone else have any thoughts. Thanks
