    Hi there new to the forum. I have been trying to solve a P0171.
    I have cleaned the MAF sensor, but code is still popping up. Got my self a smoke machine to test for vacuum leaks. I just need your expert opinion where to stick this smoke machine. Nobody has a tutorial online so I hope you guys can guide me! Or point me in the right direction.

    Thanks in advance!
    Mike
