[SPAM] Fw: Wet DD

[scirocco at vintagewatercooleds.com (Eric S)]

John,

Thinking of how the digifart system works, unplugging the O2 or the
Coolant Temp sensor causes the same "condition".  The computer goes into
open loop mode...

So, whatever component that is being affected by the wet condition must
have some mixture control function.  (IE, it seriously affects closed loop
operation).  I'm a little suspicious of your air flow sensor at this
point....try your test again only hosing the air box and see what happens.
