You should listen to me. No, seriously, listen to me.

Re: Butterfly valves stuck open?
"proper spec at 0.48-0.51"
Where are you getting that spec? Everywhere that I look it's 0.48 - 0.52 V.
The readings still don't make sense to me. He was initially reporting "208 with the key off and -0.8 with the key on". The 208 value could have been a resistance but I know of no way to get a negative resistance. Later he says "if I go below 0.54, something messes up and the reading just jumps to 500". It sounds like he's measuring voltage at first but it somehow jumps to resistance (or is that 500 V?). OP - Is your multimeter working OK and do you know how to use it? These readings and your apparent refusal to list measurement units has me wondering.
"The manual's resistance value is wrong. Unplug the sensor and adjust it to 1.5k ohms"
There are specs in the service manual for the TP sensor resistance but I can't find any for the STP. Where is a resistance spec listed?
The secondary throttle seems to chatter, both visibly and by sound, when it reaches full open in the video. I don't recall that on my K6, which is why I'm suspicious. Perhaps it's associated with a misadjusted sensor.
