    Good afternoon everyone, I have a quick question for any of you Toyota techs. 2010 Toyota Tundra 5.7 that has p0171 and p0174 codes. Is it possible the vacuum line from the brake booster being disconnected could cause those codes?
    Correct me if I'm wrong but those codes are lean bank codes I believe.
    Any help would be much appreciated.
