Q: Small leak in emissions

asked by on February 17, 2016

I have a small leak in emissions.

You will need to have an EVAP smoke test performed to locate where the system is leaking before replacing anything. It could be a stuck valve, broken hose, or a gas cap that is not sealing the system. Without knowing where the leak is, you don’t know what to replace. I would recommend having a certified technician take a look at your car to find the source of the leak and make the necessary repairs.
