What should the idle be on a Saturn?
BTW, it is normal for a Saturn to hold a high idle for a couple of seconds after taking your foot off the gas, but then it usually drops to 750. It will set a P0507 if the idle is 950 or higher for one minute on a warm engine. That is a sure fire indication that the intake manifold gasket is leaking.
Why is the idle speed of my car so high?
