Run a scan and check for any unresolved fault codes and check the alternator out put make sure the reading is around 13.5 -14 V there abouts.

if the check engine light is flashing it means a major emmisions componant is suffering . make sure the alternator and battery is good , but most signs are its a major misfire causing the engine to run lean or rich:)
