Hunting idle possible MAF issue?

Hunting idle possible MAF issue?
Hello everyone I need a little guidance on where to start diagnosing.
Driving into work yesterday I noticed my 2008 xj8 started idling weird when sitting at stop lights. The idle will consistently drop down to 400 rpm and bump back up every 3 seconds or so. I notice the odometer will dim a bit everytime it dips down. I bought a can of MAF sensor cleaner and tried cleaning it a couple of times with no difference. The car does not hesitate or stumble when driving any other speed. I'm thinking maybe the MAF sensor needs replaced but on my way home something else weird happened. My display screen started to flicker on and off for a bit. This concerned me thinking maybe the alternator is on its way out which would be odd because I put a new alternator in and have maybe put 7000 miles on it since then. Below are screen shot of the codes I am pulling when I put my code reader on it which all seem to point to the MAF. Should I start with a new MAF or are their some other tests to run first?
