Well I finally took the time and removed the plug to the ECM,and with my
VW PRO Training, fuel injection manual in hand and my multimeter in
other, I started testing ohm values.
I want everyone to know that this computer stuff scares the hell out of
me, simply because I don't know diddley about this stuff, and as far as
I was concerned, if it didn't come equipt with points and a condenser,
it wasn't right.
Anyway, I took the lid off the AFM, potentiometer, and saw this little
wiper thing, on a printed circuit board, and I, plugged in the
multimeter, in terminal 15and 19, swung the arm on the potentiometer,
and the ohm values, that were supposedly to be at  500 to 1000 ohms were
at 1700,1900, 1875, in two places, on the board, which were just as the
wiper started up the two little arced parallel contact areas.
Where this high resistance area is ,is just when the van is suppose to
start moving, off idle, exactly where I've been having the "leave from
the stop light" problem.
I cleaned it off a s much as I could, with contact cleaner, and a cotton
swab,and I will say, that the van is a little more responsive, but not
as it should be.
I'm replacing the AFM, this weekend,( or as soon as I get a new one.)
Problem solved in less than an hour!
Right proud of myself.
Easier than I ever thought !!
Hey, Maybe this computer stuff isn't so bad after all!
Will report after I install the new AFM.

Later,
