2007 hhr lt2 2.4l, I have the check engine light on, code P1174 any help please. on 2007 Chevrolet HHR

Car runs 100% fine, gas mileage has dropped over two weeks light has been on, car will blow white smoke after letting idle for a few minutes, CPU has been reset twice code pops up next day. Only thing I've tried is new full tanks of gas and injector cleaner.
