I know P0404 is probably a dirty EG R. Runs a little rough occasionally and dad just puts his foot on the floor to "try to clear it out." I shake my head, but it's his truck. Any chance the P2552 is caused by that, or am I looking at two different issues? He's going to stop and either get a new valve, or just a seal kit. I'll clean it out once he gets the parts.
