P0171 P0174
I have a 1999 f150 4X4 with the 5.4, service engine light goes on with code p0174 and p0171. These codes go on after a couple of drives after resetting them. I looked these codes up and it says bank 1 and bank 2 system lean. Any Ideas? I have checked for a vacuume leak and can not find any. Thanks in advance
