Hi.
A8 tech, thanks for your advice. I figured that the most likely place for a bockage in the intake system would be the air filter, so I changed that as a first try.
Tha air filter did seem dirty, and only when i put the new one in did i notice the difference.
It seems there is no more erratic acceleration (slight ded-spots), now pulls cleanly from ide to red-line.
I will clear the code, and see if it returns, or whether this simple fix did the trick!
Thanks again...
Mike
