7. Advisedly Spray Around Solenoids & Actuators
Look around the intake manifold and follow the vacuum hoses to discover solenoids and actuators connected to the vacuum arrangement. These solenoids and actuators are oftentimes made of plastic, which can crack with time. Spray effectually these, peculiarly if they accept axles attached to the intake manifold like in the motion picture above. Replace faulty actuators or solenoids if you discover a leaky one.

Your throttle trunk is bolted with iii or four screws into the intake manifold, or there is often a rubber or paper gasket between these two parts.
