Pulling my hair out
What little I have.
So I got the dreaded CEL and P0171 and P0174 codes. After much searching, pulling and probing I discovered the PCV hose elbow at the Intake end had collapsed and a hole developed. (this after the opposite end did the same thing EXACTLY 1 year ago. So I replace the elbow and as I'm putting it back together the PCV tube decides to break. I managed to repair the break with a section of appropriate vacuum line and get it all back together again. I start it up and its running worse than before. I let it go until I get the CEL again this time I get 1131 and 1151. More probing and searching. After two days I finally found that the metal tube the PCV hose connects to had actually come out of the upper intake! Anyone else here ever have that happen? I'm guessing the only correct fix is to remove the upper intake and properly reinstall the little tube?
