If your battery is on the blink the ECU is constantly monitoring it and will deliberately increase idle speed as the voltage drops in order to get the alternator producing more so the injection system can function correctly, as the voltage gets lower the revs at idle will increase from normal idle of 750rpm to 2000rpm when the battery has only about 8 volts left in it. Checking the battery and alternator condition maybe a good idea.
