This is related to the SAIS system. A Failure prone and useless system. What we recommend is to delete it and have the codes deleted from the PCM with a tune. As a quick fix to get it going again right now is to go to a pick-a-part yard and get a block off plate, remove the SAIS valve and block off that port just above the exhaust manifold. Pull the SAIS fuse. You can drive it like this until you can get the PCM tuned.
