I don't have any prior knowledge of similar cituations, but I can offer ideas.

Make sure coolant and engine oil, etc is correct, in the right place, and at the correct amount. Is you engine warmer than it should be or is it just at normal temps?

Wild theory: The computer sees that the engine is running too hot, so it attemps to cool it down by slowing down the engine. It lowers too much, notifying the computer, which raises the rpms to a higher than normal idle rpm. The cycle continues.
