  I had an AFM fall off my '85 on the way home from the opening showing of "LITTLE MISS SUNSHINE" with some friends. That made for a great story....

  It did work, it just ran rough and was very slow to respond to throttle so almost impossible to start on a hill. I ended up pulling over, and fixing it with a quarter (i didn't have a screwdriver to tighten the hoseclamp, only a quarter).

    Actually, you can drive around half decently.
    It's not hard to forget that last step of plugging the connector onto the
    AFM of course, which is how I found out.
    They run quite well, though unevenly, especially with a lot of pedal
    applied.
    I doubt that it hurts anything. The ECU is just temporarily confused about
    how long to hold open the injectors. I imagine it overcorrects a bit.
    Also...........WOT is a mode that bypasses some inputs I believe.  It'll run
    that way fairly well.

      Yes indeed,

      It will run, and you can even move the van around for short distances, but
      I
      wouldn't recommend it.

        I was working on the van yesterday and had the AFM disconnected from
        everything to look for a water leak in the area of the coolant
        distributor.  It's a strange leak that stops when the engine warms
        up.  So I decided to start the engine and take a look under
        there.  Turned the key and got a horrible noise since the air cleaner
        housing was sitting on the alternator fan.  D'oh!  OK, moved that and
        started the engine and it ran.  So no air going into the engine was
        going through the AFM and the AFM was not connected electrically
        either.  Hmmm, I thought.  Must be the idle circuit keeping it
        running.  I opened the throttle and expected it to die, but no, it
        revved up just like normal.  Engine was cold, so was in open loop
        mode, but still.  Maybe since it had no load on it the engine was
        able to spin up?   Seems like it would have gone terribly lean.  Any
        ideas on this curiosity? This is a 2.1 digifant.
