If you have the modified wiring harness to the air flow meter, you do not
need to add the capacitor. You should not have both installed. The capacitor
is a cheapie fix if you don't want to fork out the $ for the VW harness.
Both of these modifications are to correct stumbling at constant
speeds--they are not meant to fix the problem you are describing. If the van
now "runs perfectly," why would you consider putting the capacitor back in?
