I'm with the Duckdog - Coolant in a cylinder isn't bad gas! Who's the dealer, so we can avoid them like the plague? If it is a blown head gasket, unless you have made some aftermarket changes, it should be covered under the original powertrain warranty. You may want to get in touch with Acura headquarters and if that doesn't work, look to the great Father company, American Honda for help.
Good luck and keep us posted!
Oh, and

to AW.
