QUESTION: 2006 nissan sentra and the code is po171 also before this all a friend that works on car changed out my plugs and  sprayed carbrator cleaner in the throttle bodyto clean it

Answer
Hi Dennis -

Code P0171 is system too lean (bank #1).

Please verify that the cleaner that was used is compatible to the sensors in the car's exhaust system (the CAT and O2). Some are damaging. That also could be why it is throwing the too lean code. Have that reset and see if it returns.

Hope this helps -
