I have a 97 expedition with 5.4. Starts and idles fine but under light load Boggs down like it's not getting fuel but I can let off gas and accelerate hard and it runs fine. Scanner gives one lean code and a p1150 code. I have replaced fuel filter, all coils, elbow boot behind intake, and checked fuel pump with pressure gage. Got 45 constantly. Any suggestions?
