diagnosis help

[Nathaniel Merrill]

So, deleted codes, and before it left the garage the CEL was on again - code 2113 - hall sensor.
Drove it anyway up/down the road (CEL going on and off the whole time) and tested again  -  got code 2212 - throttle pot.
Guess I better check out the Hall wiring, etc.
