So it was your valves lol, that looks nastyyy glad you got it taken care of.
I recently threw codes for random multiple misfires p300 p303 p304 etc. Even though my car is still under warranty I took it upon myself to install r8 coil packs & new plugs. I scanned it again & came up with the same codes, took it to the dealer & they replaced all four injectors under warranty, not two weeks later I have the same problem. I have only 19K miles & it only seems to misfire at idle. I will be taking back to the dealer but starting to think this is a software problem.
Im having the same exact issues but on all 4 cylinders. I'm stage 2 as well but only have 26k miles. It does run a little rough sometimes when its cold. I'm not sure where to go after changing plugs and coils after the first CEL. That was probably 2000 miles between CEL's.
u stock?
the valve cleaning the dealer does is useless for carbon cleaning, they put solvent in the oil, gas and spray into the TB.
they did that to mine at 35,000 miles. below is my 2010 with 58,000 miles before and after a real carbon cleaning:

Yes its the latest file. I gapped them to .024 as instructed by APR. I just got PolorFIS so now I can watch in real time as they happen. Its kinda crazy how many misfires actually happen that arent throwing codes. Not sure how normal that is.What did you gap your plugs to? Are you on the 'updated' APR file?
I already used a techron fuel system cleaner with chevron 93 gas, didn't help a bit. In my case, I honestly don't think gas is the problem. I've been using the same gas for the last 10 months, this started after I changed the downpipe.
That stuff doesn't have PEA in it anymore supposedly. I just used gumout that has PEA in it, it, and my last tank was 450.7 miles or after fill up 31.6 mpg with the paper and pen method rather than the car (which said 32.2). I put it in the oil as well.
I really want to try archoil which supposedly has the ability to slowly break down and remove carbon for both diesels and DI engines. https://www.amazon.com/gp/aw/d/B00W...=1&linkCode=xm2&pc_redir=T1&tag=usacarkits-20

This is interesting, I love finding out about these things. I know you can get an engine oil analysis done, but how would we be able to get data on doing this sort of stuff?
