Dan n Friends Help me trouble shoot my DPR trouble shoot tool.

[sharpshooter33 at roadrunner.com (David Brown)]

When your talking about adjustments your talking about the idle mixture 
correct?

Does the O2 effect the mA?  What does it show when I go off idle and 
accelerate?  I'll give it a try on my next days off with mA to see what I'm 
getting and if it holds idle with the DMM plugged in on mA.

Thanks
David
