I liked Ed's post, and Chris Miller gave me some info too.  True Louis about 
testing it.  I kept the old one which from the white ash looked like silicone 
poisioning from the web site oxygensensors.com.  Kinda sppoked me since I just 
put in new silicone hoses..............

Since theVag-Com  10 data fields have about 5 for the O2 sensor, and not 
every field is out of range.........the bentley suggests air, fuel and other leaks 
to look for if I read between the lines.
The hesitation is really like a switch, on or off.
The CEL only shows up at idle (when I keep it going with my foot), not 
running around town, coupled with the stalling I'll investigate air leaks, clogs and 
the like.
