I seem to be getting a code P0404 on my '00 Tahoe with the 5.3. I cleared the code but then the truck started surging while cruising until the code came back. I replaced the EGR valve, cleared the code, and drove it around for a while. Then the code came back, I'm at a loss, anyone have an idea of what's wrong?
