moved to maintenance section, please post in the proper sub forum.
could be maf or some say any of the sensor the ecu uses in closed loop. o2 sensors could even be suspect if they have never been changed in a very very long time.

Seems to me it'd be the MAF, but can't be sure. CEL?

First I'd double check that the MAF is properly seated. If it isn't properly seated in the hole and is even at a slight angle it can do that. My car had the same random loping idle. I run with the MAF unplugged for several months, and finally realized it was such a simple fix!
