2004 PZEV motor with p2004 code
according to my local mech the IMRC is stuck open. im not even sure how this works. i found out that there are 2 of them on top of the intake and i am very curious on if there should be any air coming out of them when plugged and blown through? if so than i dont know what it could be or how to fix it. if not i tried capping the end that already had a cap on it and the car lost power about 3 miles down the road. any suggestions or questions i can answer on how to fix this?

The IMRC is the intake manifold runner controle , not sure what you mean plugged and blown through , they work off of RPM and load when you have met this criteria the manifold runner switches

You have a solenoid and a switch motor , I would check fuses , make sure you have voltage to the solenoid and vacuum
