This 2012 GMC Sierra V8 runs great, but can't pass the NY State Emissions inspection due to a pesky Check Engine Light.
It's setting several codes:
P0011 - Cam System Performance
P0102 - MAF No Signal
P0443 - EVAP Purge Solenoid Ckt.

Purge solenoid has been replaced, as well as the MAF sensor SEVERAL times!
Let's see where the data and a logical thought process leads on this one.
