So, I pulled the plugs at roughly 2300 miles. I found that the carbon buildup directly follows the frequency of misfire counts, so #4 most misfire, followed by #1, #3, and almost none for #2. Plugs were all right around .030 gap.
I installed RS7 NGK's at the out of box gap of .025 - .026 and immediately got big misfire counts on #4, much worse than on the stock plugs, You could definitely feel it missing at idle.
Pulled out the RS7 plugs, re-gaped the stock plugs to .028 and re-installed. Swapped coil packs around, traded 1 and 2 as well as 3 and 4. Previously I swapped 1 and 4. This seemed to calm things down and reduce the overall occurrence of misfire counts.
I have a set of RS3 coilpacks and a fresh set of stock plugs showing up today. I am going to test .032 gap on stock plugs and coils to see if that makes things better or worse.
Once I find the best gap on the stock coils and plugs, if there really is one, I'm going to gap the new plugs and throw them in with the RS3 coilpacks.
pisses me off the VW just dismisses these issues. Some people have legit lemmon law cases because they are going to have a difficult, if not impossible, time passing emissions. In cali we have 6 years from purchase so not a big deal for me but still......
