All: I am getting this code that the fuel to too lean on bank 2. I have replaced all parts directed to this code: 02 sensors pre-cat, disa valve, elbow tube, fuel relay switch, fuel filter, MAF sensor. What about the fuel breather vent or fuel tank corrosion. Somthing is fishy here.

The dealer has no clue what it is after $567 and still CEL. I have had 2 engine flushes and 4 cans of additive. I will add one more can of additive. Any suggestions. The car sat too long I know in Texas heat -- it was a repo. I have also replaced the TCU got damage also from sitting that long. Anyone with any advice -- the dealer can't even help.
