i have changed everything that I could change on the evap system and the P0443 code won't stay off and i am getting codes for the EGR and all my oxygen sensors now as well. I have changed the purge solenoid and the cannister valve and the EGR valve. I have tried to clear it out, but it keeps coming back on.

Check out the images (below). Please let us know if you need anything else to get the problem fixed. I don't think this PCM needs to be programmed.
