1995 Chevrolet Lumina Question: DURING ENGINE IDLEING, EGR's SOLENOIDED VALVE INTERMITTENLY OPENS?

 

Question

 Rookie

Recently while idleing at stop after travelling for some distances, my 3.1L V6 Chevy engine stumbled or stalled, but did not quit or die. There was also metallic clicking noises during stalling!

The engine OBD I scanner showed trouble codes 37 (TCC brake switch stuck "ON") and 82 (3X crankshaft position sensor signal error). Since the clicking noise sounded like EGR's solenoid clicking, and engine stumbled or stalled, can any of these codes cause the EGR's solinoid clicking and intermitten opened?

Thanks for your advice!
