Spoon Sports 5/9/2011Since the air ports are located between the intake manifold and the valves, physically cleaning them would mean removing the manifold.
Removing the manifold on an older car is little challenge to me. These newer cars are harder to work with, with everything made of aluminum, and no room to get your hand into the small spaces, let a alone the tool necessary to turn the bolt. Perfect recipe for stripped bolts, and yet more expensive repairs.
Everything is that this control is driven electronically. That is, the computer opens and closes the valve. Sludge buildup will cause it to stick open - it seems no one has one to stick closed.
The computer uses proprietary software, which seems to be unavailable to small auto shops, and do-it-yourself people. The "repair is to take the vehicle to a Dodge shop, where they will re-program your computer, telling it to cycle that valve during driving, to prevent the build up of sludge.
