Anyone encountered fuel system problems in their 04 to 05 trucks with the 5.4 liter V-8s? What kind of problems did you have? I just bought a new 159 with the tow and go package and was told to keep an eye out for fuel problems with that particular motor.

Thanks

 

The only problems I have is it uses too much gas. I don't know what a "159" is but my 5.4 with a tow package has been fine.

 

I bought my 04 F150 XLT 5.4L last October and started having stalling problems with it after 71 miles on the odometer. After seeing 3 dealers, it was fixed with a PCM flash, the dealer also made a note on the repair order that the issue was caused by a pressure in-balance in the fuel rails. The PCM flash fixed the stalling but caused an engine miss at idle which has not been repaired.
