    I have an 04,6 cyl,automatic with roughly 111k miles.
    About a month ago I started seeing the only performance issues Ive ever had since I rolled it off the lot.
    It started with a rougher idle than usual and within a couple weeks developed some periodic power loss while driving,usually at lower speeds and sometimes while at highway speed.
    After replacing fuel filter,plugs/wires and air filter,much of the problem has been alleviated.In fact,after the air filter it completely stopped for about a week before returning with similar symptoms,though not nearly as bad.
    At this point of course Im considering moving on to the distributor,and really not wanting to tackle the fuel pump as Im sure its probably in-tank as most are these days.
    Just needed some input from someone whos possibly had this issue,or could offer anything before I sink more money into chasing down the problem.
    Thanks!

    Sounds like your Air Idle Control Valve. Happened to mine, also could be a Vacuum Leak
