I am trying to figure out what is causing my lean codes p0171 and p0174 when i clear the codes from the computer they do not come on until I push the throttle half way down or more. At the half way point the truck stalls and the codes come on. At idle it is completely normal there is no misses in the truck or anything. There is a line broken off of my evap canister and i am wondering if that could cause it. I do not have any vacuum leak. I pulled off the intake cover and everything and heard no whistle from the engine. So now I am drawn down to the fuel system. Any input would help. Thanks for the answers.
