99 saturn. Car starts fine. However, after it warms up, my temperature gauge will suddenly drop to cold and the car will start to idle higher and irregularly. So far I believe it has only occured while I was idling. Car acts like it will stall, but it hasn't yet. I have been able to rev the car and it has gone away. So far the problem has been intermitant, it occured once a few weeks ago then went away. But now is back.
Any ideas or advice about what it could be? Thank you for your help.
