Paul you did tell me before but please once again. I am getting a code P0441- Emission Control System Purge Flow Fault. What do I do to fix this problem?! If any help, advise or suggestions would be greatly appreciated.... btw the car I have is an 01 S8. I soon will be posting pics of my baby still working on project "THE S8" it will look hot!

You might want to start at the EVAP Purge Regulator Valve. This is located by your windshield washer reservoir cap. Unplug the connector from the valve as shown (this is from a 98, but should be close to what you have):

Connect the leads from a multimeter (if you don't have one, it can be had for ~$10 at any auto parts store or Home Depot, etc.) to the two contacts on the valve as shown:

Set the multimeter to measure resistance. Your reading should be between 22-30 ohms.

If not, you have a bad purge regulator valve. If the reading is good, you should also check the voltage going to the valve. Put the leads from the multimeter into the connector (with the wire attached to it) and set the meter to measure voltage. Have someone briefly start the car. The reading should be 12.5-13.5V.

Also, check the rubber vacuum hoses for cracks and breaks. They may be leaking and throwing the code. Check the hoses going into and out of the purge regulator valve and the hose going to the intake manifold (your configuration will look different):
