Been having a rough idle lately. Took this off to give it a cleaning… is that spring suppose to spring or should it feel stuck? It’s a 1992 btw. 3FE.

Its a servo motor with 150 descrete positions, as a guess I'd say it would feel stuck.
See your FSM SF-section for specific instructions on diagnosing the IAC.

Stepper motor. Sequentially energizing the 4 coils causes the motor to step to the next position. It will hold that position until the next coil is energized.

Yeah. When I first crank her up in the morning, she runs like a sewing machine… once I get to operating temp and get to a stop light… she starts searching for her idling position. Already changed: MAF/Alternator/points/plugs… IAC is just my next stop.
