The root cause of the problem ended up being two issues with the TPS: Corrosion on the connector meant it was not sending signal to the ECU, and the little spring-loaded arm was keeping the throttle -very slightly- open. So now it idles where it should, hesitates a little bit but may be due to the TPS still. Either way, great progress!
