Code 101 is Mass air flow sensor is not within specs of the VCM/PCM performance check.
And can be caused by a bad map (BARO) sensor reading.
Or low vacuum.
Code 306 is engine miss on no 6 cylinder.
Check that end out.
Make sure MAF sensor has no air intake leaks and is not dirty and good wiring and plug in.
Check and fix engine miss and.
Confirm good AC Delco plugs and wires and cap and rotor.
Clear codes and see what comes back.
Also check fuel pressure.
Post back your pressure readings.
Low fuel pressure will cause engine miss and other problems.
