Removing the coolant from the TB might be something to try when the weather warms up in a couple of months.
Do our TBs have bearings or bushings around the valve flap? I would be more inclined to try it if our TBs had bearings. It is over $300 to buy a TB for our trucks with bearings.
We can't stick a thermocouple in the plenum so, we need another way.
To test this we could:
1) remove the coolant hoses
2) warm the engine
3) measure the ACT sensor with a DVM while idling, 1krpm, 2krpm, 3krpm
4) reconnect the hoses
5) measure the ACT sensor with a DVM while idling, 1krpm, 2krpm, 3krpm
6) compare the results!
For safety we should attach the leads to the ACT before the test and run them out over the fender and into the cab, read the DVM there while watching the tach.
