Thats a list of codes. Your air/fuel ratio sounds like its all over the place. Double check for vac leaks andclean your maf and air filter (get a new one if stock). If all else fails you might need a new maf and front O2s. There is a TSB on those codes, resulting from a faulty MAF. Read below...

Man seriously how many threads are you gonna make about this problem. I have told you you have an exhaust leak that is letting O2 in and messing up your o2 sensors reading.
