Another P0174 ?
05 F250 5.4 First started after engine warm up if held at steady throttle would start to buck, with just a little throttle would level out and run smooth. Finally started doing it after about 2 min. and then set code P0174. Note this is the only code that shows up.
Have been all over engine and can not find any vacuume leak, scanner readings are:
Bank 1 bank2
STFT .7 STFT 42.9
LTFT -2.4 LTFT 29.6
O2 1 .850 O2 1 .875
O2 2 .625 O2 2 .960
Any ideas where to look next?
Did find Trans shift cable was resting on top of O2 Bank 2 sens 1
TIA Jim
