[200q20v] carbon on spark plugs

[Brett Dikeman]

200q20v's will often experience a lot of running problems unless you use
the exact plug specified by Audi.  Since it's a 200q20v list, people
assumed you had a 200q20v and the wrong set of plugs.  Since that's not
the case, I doubt the plugs are the source of your problem.  More likely,
you're running rich, or having ignition problems causing an incomplete
burn.

Are you sure the "popping" isn't knocking(predetonation)? Does the engine
light come on during this popping?

(by the way, this thread should probably get transferred over to the main
qlist now)
