confused 02 SUPERCREW Codes P0171 & P0174

Replaced coil packs on #5&7 for previous codes but still receiving codes P0171 & P0174. The truck runs rough after warming up and when at idle. It almost wants to choke out when stopped and idling. I think I smell gas sometimes from the truck but I do not see any leaks around the injectors.
I am about ready to pull out what little hair I have left Any suggestions please!

P0171 and P0174 are lean codes on both banks. Check for vacuum leaks. Hoses, gaskets etc.
