At cold you have to press the pedal slightly to keep it from dying, but after 1min it will idle on its own, but at high rpms. Timing seems fine, ignition system is newly serviced.

So does it idle fine, or does it idle high? It can't do both. If the idle control gear is working, the idle when cold should be ~1000 RPM, then drop down around 650 RPM when at operating temp.
If the idle control circuit fails for some reason, the idle will be very high ~1500-2000 RPM and it'll be difficult to stop the car in traffic. The idle control solenoid is designed to "fail safe" so that if the electronics that control it fail, it'll just run a high idle allowing you to limp it home (or preferably to a workshop!)
If the idle is about where it should be and you unplug the solenoid and nothing changes, the solenoid is probably stuck in its bore.
