Well the cooling system flush, thermostat, water pump and hoses did not resolve the issue. The codes cleared on their own with the short trips but as soon as a longer trip (>5mi) happened, it came right back! I'm at a loss. At this point I could just trade it in but I think instead of getting into another car payment, I'm just going to continue driving it! There really is nothing wrong with the way it drives.
