So I feel dumb. The stock air box solved all. A/F ratio is right at 14.7 with 0 on the correction factor at idle.

Maybe after cleaning the air filter for a second time (or even third), it was flowing more air and/or creating more turbulance. So the MAF sensor was seeing less air, when more air was actually flowing by. The sensor could not correct enough for the extra air flowing by, therefore running lean. I still don't understand why this would happen after cleaning the MAF?

Thanks for all the support everyone, I appreciate it.

Dean, can I buy your air box off of you? If not, can I keep it until I get a new one? I also may be interested in you TMIC.
