[Diy_efi] DIY-WB problems

[bcroe at juno.com]

Enzo, 

Let me ask a few questions.  Did you run the test procedures 
successfully before making your actual runs?  You really need 
a high impedance meter for this, digital is best.

If the tests passed, then proceed with the sensor.  Warmed 
up for free air, use a digital meter for the following.  

What is the voltage from J12 (ground) to J8 (Vout) without 
your analog meter connected?  What does the voltage go 
to when you connect the analog meter?
