I have fuel problems when driving you push on the gas pedel and seems to run out of gas there's no power. I have changed the fuel pump and had all the codes cleared but its still doing it.
1998 ford f150 XLT with 4.6L
Check for vacuum leaks and recheck your fuel pressure and if you didn't do it already replace the fuel filter. It should be 30-45 psi with key on and engine off. Also check vacuum at idle, if 15" or below susepct a clogged convrter.

I put a new fuel filter inless then 2000 miles ago and vacuum is ok I think it has something to do with the cumputer. Air and gas mixture

Is vacuum over 15"? Try cleaning the maf sensor with choke cleaner. Then rescan for codes. Also clean throttle plate on both sides with choke cleaner. What were the original codes?
