Hello everyone,
Sorry for asking for help again so soon.
Car is a 2006 A6 with the 3.2FSI, completely stock.
Over the course of the spring I did a lot of very short-distance driving, until one day it started shaking during idle, stalling on hills, etc.
Everything involved in this has seemed very strange:
-Upon cold start, it runs like a clock. No misfires, sounds great, idles @ 1200-1400ish, drops back down to 800-850ish and continues running smoothly.
-Lambda reads rich in VCDS, and gas smell is obvious outside of the car.
-As the engine begins to warm up, the car starts to almost "stutter" a little bit, and you can feel it in the seats. Start getting a slow, somewhat consistent misfire in cylinder 4, sometimes 5.
-Once car is warm, misfires get worse than ever, and are primarily focused on cylinder 6 with the least amount on 4.
-Car seems to mostly smooth out as revs climb. You can't feel the misfires nearly as much, but VCDS still notices some.
-Misfires get worse and RPM drops when I turn the A/C on to max
-Misfires get significantly worse and car goes into limp mode when put in reverse
-The left exhaust pipe seems to give a smooth, cool, consistent "put-put-put" kind of exhaust, while the right exhaust pipe is hot, has almost no flow, and the "put-put" part is not so well defined.
Scan shows no fault codes related to O2 sensors or fuel trim or anything, however the measuring blocks show very unsettling values. Screenshots at the bottom.
Additionally, I am aware the scan shows the P0346 code, however I believe that to be a separate issue, as it has been there for just over a year (since I had the timing done).
And here are a couple of screenshots: http://imgur.com/a/C4bM5
What I've tried so far:
-Rotated coil packs (Bank 1 -> Bank 2). No Difference.
-Rotated spark plugs (Bank 1 -> Bank 2). Engine ran significantly worse. Almost wouldn't run at all. Replaced spark plugs, and idle is now smoother, however the problems still slowly creep back as described above.
If anyone has any advice on things to try, measuring blocks to check, really just anything, it would be very much appreciated.
Thanks!

What I've tried so far:
-Rotated coil packs (Bank 1 -> Bank 2). No Difference.
-Rotated spark plugs (Bank 1 -> Bank 2). Engine ran significantly worse. Almost wouldn't run at all. Replaced spark plugs, and idle is now smoother, however the problems still slowly creep back as described above.
If anyone has any advice on things to try, measuring blocks to check, really just anything, it would be very much appreciated.
Thanks!
