I did do that mod, where you take the lower honey comb off, and back the mafs screw out all the way. I'm thinking it may have something to do with that... I did order an un modified mafs off of ebay for cheap.

I put the screw up a few turns. After a few days my fuel trim med, and high are 104%. My fuel trim low is still 139%, however I'm getting 02 readings at idle.
