GenXer is on a distinguished road
I have an 01 4.4 with 126k and yes a bad MAF will cause a lean bank condition on 1 or 2 sometimes both, typically there might be a couple things going on like a bad vacuum hose to complicate things. I was able to get away by cleaning mine a couple times, but it finally died on a trip to the mountains...luckily found a BMW dealer and they had one in stock, $400, asked to borrow a screwdriver and installed it myself in 5 min in parking lot with SA & parts guy watching, guess they don't see that very often!

Bought one on ebay too, but it was worse than my old one, just trash, you were lucky.
