I have a 2008 Dodge Sprinter 3500 with the Mercedes V-6 3.0 turbo diesel that’s showing code P2007, which is an “intake manifold runner control stuck closed”. From some reading I have done, this is typically due to carbon buildup on the intake manifold ports causing the flaps connected to the “runners” to seize. I would like to know if any of the Sea Foam products could be used to free up and/or prevent these components from having carbon buildup. If so, what would be the method of application to get your product in that location to do its work? In my mind the fuel method applies too late in the sequence of operation and the oil method wouldn’t get there either. Can the product somehow be safely sprayed into the air intake at some point or via the EGR ducting into the intake? Would breaking down the carbon in the intake be harmful to the cylinders? Curious if there is a way to do try and clean out the system without removing the intake manifolds to clean them. Thank you for your input.
