Make sure you are connecting it to the proper connector. It can be swapped
with the connector for the crankcase vent heater. Instant blown switch. To
check measure the voltage. The switch connector will have 5 volts and the
crank vent gets 12.

Pulled the throttle body and low and behold..The throttle switch reads 1 ohm
no matter if it's open or closed.. Heading down to North Westy to grab
another one from Kirk and give it a try. Never figured it would make that
much difference...

Under load the ECU responds to a closed throttle switch as being at full
throttle so instead of over running cut out you get full throttle
enrichment.

Doesn't this sound like it thinks the pedal is out and its trying to engine
brake when the rpms get high?

Is a clickly idle switch conclusive?  Maybe double check continuity of the
switch at idle?

Granted, I don't understand why it would get better under load...
