If your 1986-1991 VW Vanagon idles funny you may want to check the idle control module. The 1986 to 1991 VW Vanagon has a digifant fuel injected system. The digifant system uses an Idle Speed Control system that utilizes a pulse-width-modulated air valve atop the intake plenum, controlled by an electronic module mounted behind the right rear taillight.
The part is not available new anymore, but you can find them rebuilt, or you can try to rebuild it yourself by replacing the NT185 transistor on the circuit board. You have to solder the new transistor in.
