What is your question?
Will be replacing the PCV valve & fuel filter shortly. Any other hints.

Change the fuel filter soon to verify, could also be an MAF problem.
po401? most common problem= faulty dpfe sensor and clogged egr ports. po171,po174= collapsed/split pcv tube at rear of throttle body. not saying this is what your problem is,but I have made a very good living replacing these parts with no comebacks.
Maybe they think you charged them to much! ..just playing!..
