05 f150 v6 ...... Hard to start and have to give it gas (intermittent) but always have to give it gas when I fill it up. Most of the time when I start from a stand still the acceleration is not there and it is extremely slow off the line. It eventually builds up speed and then acts a normal. Replaced the fuel pump, gas cap, cleaned the maf, reset the codes and within 5 minutes the same thing. Ask the problems are intermittent except the codes are always there. P0171, 1450, 2196 (both banks) curious whet to go from here. Thanks in advance.
