I just purchased my 88 80Quattro and am having a problem with my idle. It fluctuates between 1000 and 2000 R's. I'm new with Audi products, and am finding out how expensive(but worth the money)an Audi can be. The car has 240,000 miles, but passes Cal Smog just fine. Can anybody shed light on this oddity. thanks MBZ560SL@ix.netcom.com
