  1. 5.0 monster computer problems

    5.0L Tech
    So I'm have some real hesitation and power loss from my 95 5.0 oh. I can't tell it's definitely a computer issue. Everything turns up good with all the new senors. But I suspect the tfi on the passenger fender is going out. When I finally got the specialty tool to unbolt it. I had it tested, and...

  3. 04 GT Cold engine sputter/miss under low rpm load

    4.6L Tech
    Okay, so I have an 04 GT with the basic mods (CAI, TB, plenum, X-pipe w/ high flow cats, MAC catback, and 3.73's) I've noticed this for a while, but haven't really cared much to try to find a solution.

    4.6L Tech
    About two weeks ago I noticed a slight hesitation when in 5th gear around 45mph. It only happens when cruising and goes away with any acceleration.

  12. Replacing fuel pump. Tips, input, advice?

    2005-2010 Mustang Talk
    I'm replacing my fuel pump on my 2006 v6. I've pretty much narrowed it down to the fuel pump. According to my research the 2005 and 2006 models had problems with air bubbles getting into the fuel pump because of a part on the fuel pump. So I'm just going to replace the pump itself. So it looks...

  17. Another COP Question... FRPP COP vs FORD OEM COP

    SVT Cobra Tech
    So I've been looking around and everyone I have read posts by says any COP other than OEM is a waste of time. Do I need the OEM ones from the stealership or are the Ford Racing COPS just as good? I'm changing them because I have a hesitation under light load and when decelerating. I've...
