I believe that this is a voltage problem, I would check the continuity of the loom back to the ECU, and pay particular attention to pins in the plugs as they can become loose and corrode causing high resistance readings.

Hello did you find a solution to this problem?
I have exactly the same problem with a VE 3.6 Alloytec at the moment, and cannot find the problem. Have replaced the IMRC and still the same.

Hello,

Remove the actuator and see if the intake runners move by hand. What happens is they get dirty (coking) and stop moving and you must remove the top of the intake to clean it.

Here is a guide and diagrams (below) to give you an idea on what you are in for when doing the repair.

Please let us know what happens.

Cheers, Ken
