AFR difference between the banks

Yep. There's always potential for some variance between the banks -- not sure if .5 would be considered unusually high deviance tho'.

Can you monitor fuel trims for each bank -- how close are they?

Also, one MAF sensor may need to be cleaned or you could have one extra dirty filter.

Yeah i thought it was the filters as well so i looked at them they looked barely dirty and i have found a few tree leaves, cleaning that barely did anything. There was notice, but u can still hear that something was off. The A/F logging showed it was off by~-/+.50 from other bank. Found this post and adjusted it, now its right on the money they r both the same ty very much, if it wasn't for this thread and ppl's shearing i don't know when i would have figure it out.
