OK guys, heres the scoop.....my 2001 F150 with 62000 miles just started acting up.. ...running real rough....a buddy who is a full time mecanek said probably the 02 or IAC sensor.....took it to Auto Zone and Advance Auto this AM and both read the computer (after some argument since there was not a "Check Engine" light on and they both said their computer would not read anything if it wasn't) and both said, MUCH TO THEIR SUPRISE, Misfire Detected on Cylinder 1......so, now my question.....Is it the Plug, the Plug Wire, or Something Else......what do you EXPERTS say???????????
