Try the 02 sensor. A new one changed my V8 from a bucking snorting pig into a
silky smooth luxo machine.
Also, DO NOT buy an Audi replacement. An O2 sensor is an O2 sensor. The only
difference is the connector.
I have been using a Ford 4 wire with no problems. I would however suggest using
a 3 wire because it is easier. You should be able to find a brand spanking new
one for less than $100. The Audi part is over $200. Ouch.
