I am in the middle of replacing the spark plugs on my CL600 and I have a question I am hoping someone has an answer to. It appears that there are 2 secondary air injection control valves on the passenger bank of cylinders. The rear one has a broken barb and needs to be replaced. My question is concerning the forward one. It looks to have an open port facing the rear of the car. There is what appears to be a caped off vacuum line sitting behind the cylinder head. Is this supposed to be plugged in to the valve?
