    I have a 2001 Saturn that starts when the engine is cold but the idle is
    about 1500. While driving the rpm remains very high. After the engine is
    warmed up, it is very hard to restart, but if you push accelerator to the
    floor it does try to start. The temp gage stopped working today. I have
    replaced the throttle position sensor, but it was no help. Any ideas???
