vacuum leak question 200 1981

If your car has A/C it could be an idle control valve that allows the engine to rev up when the A/C is engaged. Try to pinch that hose so you can stop the air leak and see if the car idles better. If it does then that component is where your leak is. If you have no A/C you can plug up that line and do away with that component. If the idle does not change when you plug it/pinch it off then your leak may be somewhere else. Good Luck!

Sincerely,
