Unhappy Header install now check engine light comes on

Hey guys yesterday I had my original tri-y's headers from Clear Image installed. I deleted my air pump. Removed the relay. Plugged the hole in the breather. And now my check engine light comes on when I'm driving but goes out while it sits idle? Can anyone tell me what I need to do? Get the pcm tuned or what? Also had cats deleted.

Yes you need to disable the air pump and turn off Malfunction code in PCM.
