Is the warm engine undriveable when cold?
This time it started with an idle around 1500rpm, slowly dropped to 1k, then quickly cycled back up to 1500.

Turn on the car’s ignition and let the engine warm up. While the engine is warming, make sure it deactivates the choke linkage.

Why does my truck run bad when it is really warm?
If it is telling the ECM that your engine is cold but it is really warm, it can cause it to run poorly. Usually, if the ECT sensor was bad, the truck would restart after the engine cooled down.
