Well, it finally happened to me. My 08 FLHX went into limp mode this past Saturday. I have done some research into this problem but have not really dug into it. I have pulled off the connector on back side of the air filter to inspect it, but Dont know what Im looking for. Does anyone know of a thread on here with pics and instructions that address this or a web page that details this operation? Also, should I clear the trouble codes?
