P0171: Fuel Trim System Lean (Bank 1)
P0125: Insufficient Coolant Temperature for Closed Loop Fuel Control;
ECT Excessive Time to Closed Loop Fuel Control
Looks like the coolant temperature sensor is bad. should cost you around $30, that will probalby take care of the fuel trim lean problem as well.
sometimes 1 code can create extra problems.

A code P0171 may mean that one or more of the following has happened:
The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters (K&N, etc.) can cause the MAF to become dirty if the filter is over-oiled
There could be a vacuum leak downstream of the MAF sensor.
A code P0125 may mean that one or more of the following has happened:
Insufficient warm up time
Low engine coolant level
Leaking or stuck open thermostat
Faulty coolant temperature sensor
