Hello all, not sure if anyone else has come across this problem but I have p1004 code which is for the manifold control runner short valve. I have already replaced BOTH of the manifold controller's. Code still didn't go away even after clearing the codes. Ended up buying a used Manifold Intake due to the plastic piece that the short runner valve sits in was broken. I put both brand new control valves on the new manifold intake I bought but even after changing out the manifold intake the code is still showing. Could it be electrical? I also noticed when taking out the old manifold that the 2 bolts in the back were not even on there and one side is missing a bracket, not sure that would really effect the manifold intake though, would it?
