Does anyone know how to test a MAF sensor? I have a stock MAF sensor that I believe is going bad, or it may even have already gone bad. I would like to test t prior to purchasing a new one.

I have a 2011 GT500 that was running for months at an AFR of 11.8 at WOT and the AFR of 14.6 idle and cruise. For some odd reason the car started stalling on me, so I tested the AFR, and idle/cruise is at an 9.4 and WOT is at a 10.2. After more troubleshooting the MAF frequency was jumping all over the place.

Any advice on this would be greatly appreciated!
