TRUCK RUNS GREAT BUT LOW RPM AT IDLE and cranck a lot to start on 1997 Ford F-150

IN ORDER TO EXTRACT TROUBLE CODES, IS THERE A SPECIFIC PROCEDURE TO FOLLOW?
OR JUST HOOK UP THE OBD 2 SCANNER

when you plug in the tool, follow the instructions on the tool to retrieve the codes.

THANKS
sounds to me like it is just idled way low and you just need to take it in to someone with a scanner and have them idle it up and its cranking allot probly cause it isnt getting mutch gas or check plugs
