P0171 Fuel trim lean Bank 1

Check the sparkplug condition, a over work sparkplug or even a loose sparkplug can cause this concern.

 The valve cover can leak oil into the sprakplug well which can cause a slight misfire condition and set a lean code without setting a misfire code

 Worn sparkplug can also set a lean code condition
