I'm having very similar issues. I've had a lean code for one of the banks only, and one of the O2 sensors from the same bank. I then cleared the codes, and drove for a full day before getting another one. The code then said I was getting too much air through my intake, which basically means I'm running lean still. I will go through and check my intake for any leaks, and clean the MAF. But I have a feeling it's something else. Come to think of it, this happened after checking my oil...I can only hope that is the problem.
