2 codes p0171 and p0174 (bank 1 and 2 too lean)my truck is sputtering and spitting all through the rpms unless i floor it and was wondering if i need to get a new fuel pump. i googled the codes and i dont think i have a vac leak and it says a good chance its the fuel filter but says nothing about fuel pump... what you think.

sound and vid quality suck but you can tell when it sputters and after i was done taking the vid i went to turn around and then it died on me in as i was hitting the throttle in reverse but it fired right back up and sputtered on home.

i am having the same problem did u ever figure out what it is?

 

Ouch that sounds bad... Iunno what that could be, all i can suggest is that maybe you may have a leak of some sort, maybe installing a new fuel filter.

 

This might help you out......maybe

Mine will ever so often start up funny like it almost dies but catches itself. It's never sputtered while driving.
