P0170....Fuel Trim (Bank 1) from reading the code it is about fuel and its the mixture isnt correct ,this i think is being caused by a faulty O2 sensor on bank one but as iam in europe and out gallants are normally a 4 cyl engine i am afraid i couldnt tell you whats bank one weither its the left side or the right side but if you can find out what side is bank one then its just a case of testing the O2 sensor with a automotive meter then changing the appropiate sensor as theri are two sensors fitted one before the cat and one after but without a tester on it its difficult to say but i would check the after the cat sensor first.
