Check the plugs. If you replace go with NGK v-power or ac delco. For the idle, clean the throttle body and IAC valve. That means spending some cash on a 20 dollar tool kit at wal-mart and some carb cleaner. make sure your ects isn't the nylon one that was stock. If not, replace the ects with a brass tipped one from
www.saturnparts.net. If there is an autozone in your area, get the codes read there (it's free) and post them. small chance you may need a new 02 sensor.
