Car still stumbling... <<<<< HELP >>>>>
Replaced O2 sensor with real audi one, 5 new F5DP0R plugs, plug boots are 10k miles old. one new coil in the #1 spot, new fuel filter, and a different set of injectors (thanks to Chris Chmabers), and the car still stumbles. its very intermittent. it'll do it at 80mph or at a stoplight. ANY ideas?

Power Output Stage.....there are 2 of them on passenger side firewall.....
you can see the coil wires go into them. Sounds like that's your problem. Takes about 10 mins to replace.

POS=power output stage, tells your plugs when to fire
I had one go bad and had the same symptoms as your describing so I replaced both of them. Are you living close to any S car owners that you could swap them out with, takes about 2 minutes. As far as my wheels go, one has a crack in the inside lip, I'm gonna try to get it replaced or a local shop will weld in for $55.

get ahold of AudiTaki, S-CAR-FAN, Keith Maddock or any other URSer on dtwaudi
someone would be more than happy to help out, I would but I'm 300 miles north. contact Keith, he's been down this road I'm sure.
it'll be all good
on another note, has anyone come up with a plan to protect these from heat and vibrations? could they be relocated to the pass. footwell?
