Well that didn't fix it
Posted this in another forum and thought why not here too.
Quick story, truck has had cel on for quite some time now. Showed p0171,p0174 and p0401. So after checking all vacuum lines and hoses and spraying carb cleaner on the intake and finding everything ok I start searching and find that those codes go hand in hand with the dpfe,egr. So what do I do? Of course I went and bought a new dpfe. Cleared the codes and drive it throught two cycles and on my way home guess what shows back up? Right, cel!!! Now I guess I have to TRY to get the rusted egr and pipes off my rusted manifold.
Any body have any other ideas? I'm at a loss and dont want to spend all that money for egr stuff.
