P0440 Evaporative Emission Control System Malfunction What would cause this? I have no EGR, most of the AIR system has been taken out(I still have the pump hooked up) but all of those related items have been tuned out of the PCM.
I've been without these items for quite a while now. I ran into the store to get something real quick and then when I started it back up that code was hitting me in the face.
Also, Scanmaster users, how do I clear codes using it?

The gas cap wasn't on tight. Thanks!
