If it is not a vacuum leak or the collapsed hose/elbow that is so common on these engines then I would do a Seafoam treatment (including the sucking up of the fluid through a vacuum line). I suffered low power, low idle and horrible mileage and did all of the usual stuff to fix, to no avail. I don't normally go for the "treatments" but I thought "what the hell" and gave it a try. What a difference! My engine has as much power now with the a/c on as I had before with the a/c off. I went from 450km per tank to 510km per tank on the next two fills. Engine runs smoother, idle is steadier and I am a lot happier.
