How did you flush the system? Did you flush out the block or just the radiator? Total system should be about 3 gallons.

Do not run the engine any more! Drain the oil and check it closely. If coolant is getting into the oil you'll kill the bearings!

OK, so stay away from the shop! If the leak is that bad then the collant system should most likely (not 100% always) not holding pressure.

If your getting white smoke and what appears to be oil ( could be coolant in the exhaust "washing out" carbon) but you have issues. It probably also killed an O2 (why idle is screwy).

At this point, I'd pull all the plugs and look at them. Remove the Ign and Fuel injector fuses, and turn the engine over and have someone look for fluid spitting out 1 or more of the spark plug holes. Then you want to do a leak down test on each cylinder to see if you have warped or cracked the block or a head.

Sorry, but this does sound like it's going to be a pretty serious issues, but lets hope I'm wrong! But for now you have to check the engine is not badly hust before you run it and look for what caused it to overheat.
