Are you sure it is a v8? The 4.6L and 5.4L didn't have an IMCC option on it. The 4.2L v6 may have had it. It's an intake manifold control system that works in conjunction with the EGR system. There should be a rod on each side of the intake, just before it attaches to the heads. The 3.8L engine on other models had issues with the clips falling off the controllers. If they are vacuum operated, the vacuum pod may be bad. You can test them using a vacuum pump. All three codes are related to this system. Test the pod and check the clips, then post back and we'll go from there.
