I do not think an exhaust manifold will cause a problem with the IMRC.
Here is some good information:
Note:
When installing the IMT actuator, make sure the bearing (D) is in place.
Make sure the IMT assembly does not interfere with the intake manifold (E).
When installing the IMT actuator, replace the O-rings (F).
Apparently you must install the IMRC a certain way. Here is a guide to help you see how to check the wiring:

Please let us know what you find. We are interested to see what it is.
