Hi larrissanelson,

If you have not checked the following, try them.

1. Fast idle valve. Should be fully closed after engine heats up. Could be open if it has worked itself out of adkustment. Checked foe clogged coolant hoses through it.

2. If coolant level is low, this woud happen.

3. Stuck open thermostat. Engine is running below operating temperature.

4. Idle speed out of adjustment.

5. Check the brake booster for vacumn leakages.
