Change your Air Filter its probably Dirty. Get a K&N or Spectre air filter it helps alot.

Those are NOT codes. You have to pull them with a scanner from the OBD II port, go to a chain auto parts and have them give you whatever code(s) show up, first search it on your own (Google etc....), then come back here and let us know waht you found out.
