taubr unit

Its a '04 2wd 5.4 w/ 55,xxx miles When i was buying it 6 months ago i heard like a knocking/ticking noise coming from under the hood, sounds like a desil. I got asked a few times if it was desil, even from a girl, lol They checked it out before i bought it and the one tech said.. "the new ohv motors are pretty noisy and this is common". So ok, it has a warrenty with it till 100k so im not that worried bout it. Well now if i crack the gas like im getting on the e-way or passing someone it hessitates then goes for a sec. then kinda looses power. Still runs smooth just no ***** really, as if im pulling a 4 ton load behind me. Then it did it really bad and had almost no power all the way through a intersection then cleared up kinda. Any thoughts? mabey a fuel filter? Or engine problem? Sticking valve mabey? Id hate to bring it in and for it NOT to be covered under my "powertrain warrenty" if it was something else i can check out first.

My truck was doing the same thing. Last weekend though it got worse and it would only go 20mph. I got it towed to the dealer, they said #5 cylinder has no compression so they have taken the head off to inspect it and thats the last I have heard so far. Im calling them tomorrow for more info, but I think it started will a stuck or collapsed lifter.

Taubr--I had what sounds like the exact same issues. Felt like my engine was just choking or something. RPM's were there, but no power. I cleaned injectors, replaced fuel filter, air filter, had major tune up, and even replaced the catalytic converters. Converters helped some, but it is still way too sluggish. The knocking is likely the cam phasers. You'll find posts all over this forum about this "known" issue with that motor.

I promised myself I would not be back but I had to help you out thats the same thing that happened to my motor to a dime. I have a 2005 with a 5.4 . I have a ford warrenty and i just got a answer from my dealer today thank god for my warrenty they said fords going to give me a long block (new motor) $7000 with labor . This new dealer that I'm working with is the best people I have ever talked to. The tech is so helpfull and the service manager is the best. Let us know what you find
