    I have a 1999 f-150 4.6L. Just recently started having idle surging as well as while it's in gear. Any ideas what might be causing this? Thanks

    I'd start with your idle air control valve. Should be somewhere on your intake or throttle body. Get some idle air control valve cleaner and clean it, it should help, or for like $70 you can replace it.

    Have you also had the torque converter checked?
