    Engine P1151 & P1131 appeared and I need help

    I have a 2003 Ford Mustang GT and as I was letting it warm up for work. I noticed that I had a check engine light for P1151 & P1131 and its saying that the car is running lean. The car is running poorly and I checked the fuel pressure "30psi" and the vacuum lines and there all good.
