Subject: Re: Poor running 3B
Limped over to Anderson Motor Sports on Monday, Chris had a used MAP, plugged
it in and all is good again. (gave me a deal on it) Cleared the codes with his
reader. The codes I was getting were injector 3 (new) and to old recurring
codes O2 sensor and Idle stabilization valve have not reoccurred. Never did
see a MAP code however.
This has always been a great shop, one of the Owners has had a 91 Avant
forever.
Thanks all for the input, all is well in my Audi world (for the moment)
