How are your spark plugs and fuel filter? Any vacum leaks? What's rough mean?

Re: The idle jumps up and down when warm

I got a '92 80... had the same problem. After an Audi dealer quoted me $1000+ to fix the problem(which included several repairs which were totally erroneous). I took it down the road to another place. Had the oxygen sensor replaced, still had the problem... then the fuel distributor control unit... still idled funny. Found out there was vacuum leak. Haven't had the idle problem since... go figure?
