need help F250
I have a 1992 F250 6 cylinder fule injection. When the engine reaches normal operating temperature, the RPM starts to rise and flactuate. Would you happen to know possible cause and any recommendation. By the way I lost my owner's manual which makes it the more difficult. ANY help please. Thank you
