Fuel issue n20

I've been having a weird issue with my f22. For a while now I've been getting a p0171 lean code and the car stutters under heavy throttle in high RPMs. I also got a p10fa code once but hasn't come back since. Now I have just recently been able to use a diag tool on my car and the fuel pressure is reading 1400 psi at idle when it should be around 700. The fuel pressure sensor is brand new so it should not be that. Does anyone have any ideas?
