    Hi guys just installed an oil catch can.
    Got a p0171 code after the test drive which goes back to vacuum leak or pcv valve.

    Any help

    Check for any loose hoses that you unplugged & slightly wiggle all connections are tightly on first. I had a catch can installed 2 weeks ago and suffered the U0100 cel code, it was an unplugged hose. So the pain is still fresh in my head.

    Could be a misaligned part or clamp too;).

    But it definitely is caused by something not being reassembled right(y).

    Yes thanks guys.
    It wasnt the breather type but had a clear tube on side to show level which was leaking. Re installed now ok.
