P0171 after individual fuel injector replacement low power at low speed and excessive fuel consumption. Coils and plugs are good. Feels like a cat suffocation but after loosening the manifold still has not relieved the hesitation and power loss

Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
The check engine light will flash when the PCM (computer) sees a direct engine misfire and the code P0171 is a lean code. I would start with checking the fuel pressure. If you can give me the year, make and model as well as engine size I can give you the pressure specs and we can work from there.
