[V8] Dizzy Hall sensor, knock sensors

[kyle leatherwood]

John, I had a local V8 do something similar, as well as begin to surge at a certain point.  Ended up the hall sensor in the dizzy shorted out, and when it did it melted some wiring in that harness.  When the wiring melted it also melted the wiring to the coolant sensor on the back side ode the passenger side head.  Same codes youre getting.  I ended up having to replace the dizzy and re wire hall sensor wiring and the coolant sensor wiring back to the ECU.

May be of help and may not be, just my 2 cents.
