Pedal position sensor supply voltage code??

[graphite9]

I just got a plethora of codes on my 98 M3. This set has come up once before. Im not even sure where to start with this? Any input would be greatly appreciated

codes:

Pedal position sensor supply voltage
CAN timeout, EGS
"Catalyst efficiency below threshold, Cyl #1-3"
EVAP large leak detected

..I do have a misfire/stumble when going from idle to throttle.
