Hi All,

I had "Vanagon Syndrome" (bucking and uneven power delivery due to
mixture problems from a failing air flow meter (AFM)).  In 8/2018, I
replaced the AFM with an offering from one of our favorite vendors,
which was a rebuild by Fuel Injection Corporation of Tracy, CA, and
had the magic capacitor added internally.  Syndrome cured, for a time,
but here I am just ~12k miles and 16 months later with the same
symptoms returning.

One thing different about my installation (I-4 swap) is that the AFM
is mounted upside down (plastic cap down) relative to what I believe
to be the normal orientation.  Does anybody know if this could be the
culprit?  The original AFM had, I believe, lasted the PO a long time,
but failed maybe 1-2 years after I changed the orientation.  I also do
a lot of off-road driving, so vibration could also be an issue.

Any other ideas?  If I have to re-do my intake to change the
orientation of the AFM, I think I'd like to consider other options.
Has anyone had luck running MAF conversions (e.g., the offering by
Split Second) with Digifant II?

Alex

P.S. Still looking for leads on that 548mm axle:
