Fellow Audi Fans!, I have noticed that if I disconnect my O2 sensor the car runs richer, and therefore faster, it also runs much better when cold. So my question is this: would it work to make a switch so I could engage or disengage the o2 sensor? This might not be neccasary if the enrichment unit worked properly, but I'm not sure it does.
