The P0440 code refers to a general issue in the Evaporative Emission Control System (EVAP). So, there is a leak, I would check the gas cap first, but since it starts funny, I have seen the EVAP purge solenoid go out and stick open. Here is the location of the valve, remove it and try to blow air through it, if so, the valve is bad, you should not be able to have air pass through it without power to it. Check out the images (below). Let us know what you find.
