Engine vacuum leaks may develop from the various vacuum hoses causing the engine to idle incorrectly or the Check Engine Light to illuminate. Damaged vacuum lines should be replaced as necessary. Our technicians tell us that rubber vacuum hoses can be used to replace damaged plastic lines if necessary, as long as any connections are vacuum tight.
