Ok, so I did a little testing.
Looked under the hood today to see what the IMRC was actually doing. The runners were stuck in the open position at any RPM.
Disconnected the IMRC power, started the car. Runners returned to closed. Shut off the car, plugged the IMRC power back in. Started the car. Worked fine.
Revved up the car and watch the runners open and close at the correct times. So everything looked good. Let the car idle for about 1 min, and watched the cable. Randomly after about 1 min, the IMRC pulled the cable to open the runners. This is just sitting there at idle.
I repeated the same thing over again. Worked fine again for about 1 min, then the IMRC pulled open.
Why is my ECU telling the IMRC to open at idle and stay open for good?
