Sorry about that I had it in my head you had a hhr. The code P1682 ignition switch circuit could have been set from crqnking it without it starting and the battery voltage dropping too low. There is a bulletin for that code setting because of that condition. The P0300 is random missfire the P0443 is evap purge solenoid control circuit. The P0102 is mass air flow sensor performance. The P0102 can be caused by the same reason the P1682 can low battery voltage.I would have the battery tested make sure the alternator is charging properly also make sure the battery cables are clean and tight. Also have a back pressure test done to make sure you dont have a plugged cat. That could set a random missfire code the mass air flow code etc.
