2005 Saturn L300 Engine Warning light P0175

I have a warning light on and I took the car to Shucks as they let you use the diagnostic tool for free (I have very limited income as of late) and it showed only one code which was P0175 with an explanation of System to Rich Bank 2.
Also the engine with reduced power light will come on at times and run with reduced power, after shutting down for a few minutes it will run fine. Also the Traction Control will not work on console excepting for just before reduced power problem the Traction control light will come on. I'm not sure how the two are related but they appear to be.
Could you shed some light on what this might be?

Please and Thanks in Advance,
