I made a quick trip to AutoZone and got these trouble codes:
A) P0449
B) P0300 - Possible bad engine coil CAUSING MISFIRE
C) P0102

P0449 (Mass Air Flow) can cause a random multiple missfire (P0300). A bad ignition coil would typically cause a specific cylinder missfire, along with the cylinder that shares that coil pack.
The P0102 is just an evap code, most likely caused by a loose gascap.
I would suggest clearing the codes by disconnecting the battery for 10 minures, take the car for a ride to trip the check engine light again, then see what codes are in there again.
