if you get a high voltage reading you are on the wrong wires
use a paper clip as a pick up probe
I put the screws in the middle of the adjustable slot on the TPS
if there is no improvement I do small adjustments
left or right
in the dark start the motor up
and look for arcing or sparks on the coil and leads
ECU maybe at fault if it doesnt reset
get one from a wrecker
