E-vac leak on a 2009 Chevy Malibu.

[Paul Brennen]

Check engine light will not go out. I do not know the code. The readout tells me I have a large e-vac leak. How do I find it to be repaired?

The best way would be to smoke test the whole system. There may be 1 place what may leak, but I have seen actually vehicle with 2 leaks. Being said smoke test is the easiest way to go.

If it’s large smoke can be seen, or the engine can behave differently.

Those job require specific equipment. Not to discourage you

Peace
