Engine Overheating and P0171

So my 2001 Formula (ls1), has been overheating a lot lately and I cant figure out why. It will run normal (about 180-190) for while, but when I begin driving around it will slowly increase. When I bought the car in May this year I had a brand new radiator put in and I check the coolant which was fine. I also have the p0171 code (system running lean) but I checked my pcv line and cleaned the MAF but the code keeps coming back. It isnt on ALL the time and will go out randomly.
Any help would be appreciated!
