came in with an IMRC (intake manifold runner control) stuck open bank 1. Found the solenoid to be defective. Changed solenoid and vehicle came back with same code.

I have good power and ground, can activate/deactivate imrc via scan tool, wiring is good and no vacuum leaks. When I start the car with the solenoid unplugged, circuit is activated for a couple of seconds then deactivates.

With the solenoid plugged in, it engages and I can see the actuator moving. I can unplug the solenoid or vacuum connection at solenoid to verify the actuator linkage is moving. If I unplug the source vacuum of the solenoid and leave it unplugged for a couple of seconds, the solenoid deactivates. otherwise it does not.

any suggestions? What else should I look for?

You have a wiring diagram for the system?? Maybe it has a position sensor and the voltage isn’t changing while the actuator is moving

Which code are you getting, specifically?

I agree with Cheryl. It sounds like whatever feedback sensor the PCM uses to gauge if the IMRC moved or not isn't happy with the IMRC performance.
