Ok, sorry for the delay, but I’m far from a teenager.
This car has, for lack of a better term, two vacuum solenoids. The one on the side seems to be intended to do something with the throttle plate, but doesn’t. The other is on the back, and seems to open an air passage, which makes no sense, as it wouldn’t be filtered.
I checked the condition of the throttle plate, and it isn’t bad. Neither the air filter.
I disconnected the vacuum line on the rear one, and no change, nor was there vacuum on the line. I’ll try activating it manually and see if that effects any change.
Dual Point Fuel Injection. Might be a mid year, no idea but the intake/throttle body is quite different from your vid.
I did a reset on the ECU, ad the idle dropped to 2-3K.
I do miss the points/condenser, carb days.
