It just might be throwing a fault code in the O2 sensors from a MAF issue... doesn't seem logical since it's a computer, but the oxygen sensors and the MAF have a very close relationship.

My mechanic had his PST tool hooked up to my car to diagnose a CE light and it was an oxygen sensor. It was making the MAF read bad too and one might think the MAF was gone as well.

We replaced the O2 sensor and the MAF's readings started to stabilize and looked great.

So do have the MAF temporarily swapped out to see if it might be causing a sensor to throw a code. It's certainly worth a try.
