O2's 900+ at idle

[tenright]

Ok I'm stumped....car runs great, BLM is at 128 or even 129 at idle, MAF is 6 grams, but the O2's are 900+...I don't get it 900's are pig rich yet BLM is adding fuel at 129. INT is 128 and I have a TT chip....FP is 43 line off.

The car also has a 3.5" LS1 MAF and translator not sure if maybe that has something to do with it. Any help would be appreciated.

Ya, that reading the 02mv at idle is pointless. Rich/Lean/Rich/Lean.

Car is fine.

Well I had run a couple of tank fulls of mixed 100 octane through it and apparently the O2 was carbonated pretty badly..I cleaned it up with carburator cleaner and the O2's are 750 or so cruising and 800-850 at idle. Much better....
