IS THERE SOMETHING GOING BAD THAT CAN TIE THESE CODES TOGETHER? EXHAUST VALVES?

They could be related. A bad maf can cause misfire codes.

Check the maf for correct operation, via scan tool or digital multimeter.

Check the ignition system in case the misfire is due to faulty ignition components.

Check your fuel pressure as low pressure will cause a misfire as well.
