I added to my post. Was it a bosch part #? Some of the after market ones don't last long.... Rough idle is usually the CPS. Rarely is it the cam sensor, but they can go bad. I would try the CPS. It may have come loose. It is a difficult area to work in, get the plug connected properly and making sure the bolt is tight. Check that first, then I would replace it if it didn't come loose...
