    Q:
    How to check and fix a vacuum leak at the bottom of the throttle body? Posted by Customer
    A:
    The TBI throttle body is attached to the top of the intake manifold by two bolts. They can sometimes work loose from vibration and temperature changes during normal engine operation and cause a vacuum leak. If you suspect a vacuum leak exists at the bottom of the throttle body, use a rubber hose as a stethoscope. Start the engine and place one end of the hose next to your ear as you probe around the base of the throttle body with the other end. You will hear a hissing sound if a leak exists, but be careful of hot and moving engine components. Remove the air cleaner assembly. Locate the throttle body mounting bolts. Decide what special tools or adapters will be necessary, if any, to tighten them. Tighten the bolts securely and evenly. Do not overtighten them, as the manifold threads could strip. If, after the bolts are properly tightened, a vacuum leak still exists, the throttle body must be removed and a new gasket installed. After tightening the fasteners, reinstall the air cleaner and return all hoses to their original positions.
