Troubleshooting Stumbling / Hesitation issues

[Atwalz]

I have same issue. I also ordered vaf connector which I plan to replace. While the motor was running I measured the voltage signal inside vaf meter and external plug. Connection was not solid and reading were lower at external pin. By removing the 2 screws and bending the pins downward helps with improved connection. I even messed around with spring tension to change the rich and lean settings.

3rd pin from left is blank and not used.

I need a diagram of the connector all the way to the ecu to fix this one lol

Check out the following post, at the bottom of page 1 they have a bunch of wiring diagrams and other information straight from the FSM. There's other additional information on following pages all about the stock VAF.
