MY HUSBAND HAS A 2014 CHEVY SILERADO THAT HAS BEEN TO 4 MECHANIC SHOPS AND 2 TIMES EACH TO THE 4, ONE WAS ACTUALL THE DEALERSHIP AND THEY COULD NOT PIN POINT THE PROBLEM .  CHECK ENGINE LIGHT WILL GO OFF AND COME BACK ON WITHIN MILES OF DRIVING, LOW POWER DIMMING INTERIOR LIGHTS DOESN'T EVEN MAKE A NOISE WHEN PUTTING GAS ON , THE CODE IT KEEPS THROWING IS P0506 , WE HAVE HAD THROTTLE BODY REPLACED AND REPROGRAMED , FUEL INJECTORS CHECKED , TRANSMISSION IS FINE.  HAS ANYONE HEARD OF SUCH A PROBLEM AND COULD IT BE IDLE AIR CONTROL VALVE?  ANY SUGGESTIONS WOULD BE GREATLY APPRECIATED.

I'd monitor voltage during these episodes. If the alternator is going bad, low voltage would cause all sorts of problems.
