I will be cleaning it tomorrow when my new filter comes in.

So now that you've read those threads, what have you done to troubleshoot the problem?
Past Subies - '11 STI Limited stage 1+ and '04 STi stage 2+
'13 Wrangler Rubicon - custom front bumper w/12k lb winch & off-road lights, skid plates, diff guards, etc.
'04 Porsche 911 Turbo GT2 clone 600 HP/TQ
'77 F-150 heavily modded for off-roading
It was not just the engine, intercooler,turbo,radiaotor,all maintenance,heads resurfaced + valve job, and many more I cant even remember at this point. What I will be doing tonight after work is cleaning maf. The misfire code came on when I attempted my first pull, car idled fine when I stopped and drove home fine. I shut the car off and turned it back on and code was gone. I have a fuel pump,one step colder plugs, and air filter that will be going on sunday. If none of that works then off to the dealer I go I guess.
