There is no governor.
You cannot adjust speed control.
What exactly are you attempting to accomplish.

Hard to diagnose without access to the vehicle, but I would try cleaning the Mass Airflow Sensor

I found 3 recalls, NHTSA Campaign number 04V586000 Diesel Fuel System; NHTSA number07V063000 Brake Light Switch; #08V156000 Fuel System, Gasoline Delivery. There are also 33 Technical Service Bulletins. These can be found on the NHTSA website or at your VW dealership.

Start with replacing the fuel filter. When they clog up they will keep pressure but not flow.

Take it to a shop that can tell you what code it is setting and you will have your answer. Many auto parts stores do this for no charge.

BUICK RENDEZVOUS IDLES UP REALLY HIGH...WITHOUT PRESSING GAS. WHAT IS THIS?

fuel filter or air filter clogged.
did this help?

hi press. switch on compressor could cause problem - there is a service bulletin for this - i will be testing a 2003 buick tommorow for this problem

The fluid in the versa trak AWD in the rear is old and needs to be drained and refilled. After you drain and refill it, make a bunch of sharp left and right hand turns, then drive it for 10 minutes. Drain and refill it for the second time and problem solved. Use only versa trak fluid available at any GM dealership.
