[V8] Blink Code 2121

[Ron Wainwright]

Rich, Book proceedure to check the Idle switch is as
follows,
prob terminals 4 & 6 of the connector....you should
get 0 ohms (continuity)

 Activate the throttle (book states 10%) while still
probing the above terminals. You should get infinite
ohms (open).
 Says if that value isn't reached to adjust the
switch. & if the value can't be acheived to replace
the switch.

 But I say you might have some water/condensation
inside the connector. Since the connector is @ the
front of the motor rain/dew/ect, creep inside the
rubber connector cover that hides the wires. So the
connection gets compronmised.
 Good luck

 Ron on the brink of haveing the best V8 in the
States...IM VERY HO BUWAHAHAHA
