Erratic idling and stalling when I 1st press the throttle, lots of black smoke out the back so over fuelling to death. I have been outside for an hour with feeler gauges and multimeter....I'm ready to explode now though, just cant get anything like what I should be getting reading wise.

What exactly is the problem?

So you think the tps is the source of the problem? Don't think it is man. Anyway you can calibrate the tps by flooring the accelerator pedal with the ignition off, hold it down, turn the ignition on and hold the pedal down for a minute.

Well i did the reset type with a feeler gauge and messure the pins. for me i was always within tollerance told from the TSRM if you aren't iam guessing that either you did not set it up correctly or you have a broken TPS
