Vacuum leaks allow unmetered air into the intake manifold, causing the ECU to run the engine lean; symptoms include rough idle, high idle speed and hesitation. Diesel and hybrid vehicles use a mechanical vacuum pump for brake servo assistance, which can also fail. BRISTOL 603 vacuum system repair costs $379–$693.
