i hope its just the bleed set wrong,
a fast test for the TPS
is at pin 2, (to ground) volt meter.
in pin 1 is bottom
pin 2 is idle switch, it will be at 0v, for idle and move throttle a bit and it goes to 5v fast. if at 5vdc all the time its set wrong. (back probing pin 2)
Pin 2 Idle switch out Blue/white (0v when at idle 5v off idle )
here is the lay out for TPS, some GM books show it wrong.

also , if lucky the DMM set to volts and connected across the ISC pins
6v is the average DC voltage reading for 50% but some meters dont like this square wave (band width issues) and read wrong. or have too slow a sample rate.
