Common Symptoms

When an engine has a vacuum leak, it may:

1. Idle rough

2. Be hard to start and/or keep running when cold

3. Misfire

4. Hesitate under acceleration

5. Get poor fuel economy

The Check Engine Light may illuminate setting a P0171 or P0174 code, indicating that the fuel system is running too lean due to the vacuum leak. 

Best Practices

When locating a vacuum leak, we recommend using a smoke machine to find all of the areas that are leaking. 

After all of the known vacuum leaks are repaired, we recommend performing a drive cycle test drive to verify that the air-to-fuel ratio has returned to normal.

Common Misdiagnoses

Vacuum leak symptoms can be caused by a defective mass air flow sensor, ignition misfires, a defective idle air control motor, or a stuck-open EGR valve.
