So what is this in english?
What can I do to fix this issue?
I already checked the fuel cap.
Thanks.
More than likely you have a vacuum leak. Sometimes you can start the vehicle and hear the hissing noise. If you have a 2.0 SOHC engine, I would be willing to say you have a vacuum line leak at the back of the engine where the PCV line hooks to the intake manifold.
