2005 5.4 help!!
My 2005 5.4 f150 is about to drive me nutts. I'm hopeing some one on here can help give me some pointers. It will only take very light throttle. I've replaced the fuel filter fuel pump fuel pump module tps sensor plugs the coils and no luck. If I give it wide open throttle it will take off hard fall on its face for a second then goes back to accelerating hard again if I just continue to hold it at wide open throttle. Any help is greatly appreciated.

I'm making a WAG that your CEL is lit up, probably has been since all these problems first cropped up?
Have you had the DTC's scanned and recorded them?
Instead of replacing parts thought to be the cause motors with ECM's and the OBD-II monitoring capability solving performance issues begins with discovering what's causing them. Swapping out every part one-by-one is not only highly ineffective its costly without reason.
