I would suspect you have blown a head gasket. Check for coolant in the oil. A compression test will verify if you indeed have a blown gasket. ==ANOTHER ANSWER== When an engine overheats you run the risk of causing serious damage. You'll need to run a compression test to find out if the head gasket has been blown. Overheating can result in a warped head which causes the gasket to fail. If you have low compression in any of the cylinders but especially any two adjacent cylinders, you will need to pull the head.
Suspect a bad coil or failed engine computer.
