My 1998 F150 4.2L V6 145K miles has developed a stuck open Intake Manifold Runner Control Valve OBD code 1537. Has been suggested by mechnic who attempted to conduct annual inspection that it is likely gummed up with cabon based on their experience. Looking for the does and don't of repair/replacement of the IMRC from those who have done this before. Thanks in advance for any and all helpful replies to this post
