1999 Ford F-250 With a 5.4 Triton V8
I just bought a 1999 Ford F-250 5.4 triton as a work
truck. It’s a manual. It’s fine for first and second but
once you go into 3rd it has no power it takes a little
bit to get up to speed and once you get up a hill it’s
crawling. It acts like the motor runs just fine but just
has no power.
Scan for codes and have the cats checked for excessive back pressure.
