Default Bad Maf?
Getting Lean errors on Bank 1! Maf reads 4 g/s at idle but only 90 g/s at WOT 3rd gear 5400 rpm! Block 032 reads fine 0.9 on first block but -21 on second block. Is this the classic bad MAF?

Default could be the MAF or o2 sensor
Have you tried cleaning the MAF? I'd start there.

Default I would have to say the maf is bad if it cant read above 90 g/s.
What year is your car? Because at that point you might be better off with the maf unplugged.
