2000 Ford Explorer

The check engine light came on and when engine is under load such as highway it will not accelerate when you give it throttle it spits sputters until you let off throttle the engine codes are P1131 P1150 P1151 PO171 PO174 Which all seen to indicate the system is running lean is there some common reason for this like a sensor that will cause these problems or where do I start to find the problem
