Q: Car started sputtering while in traffic, felt like it was losing power and there was a gas smell coming in the car, what happened?

Hi Pedro. Thanks for contacting us today. There are a few possible things that can cause these symptoms. The most common would be that you have a mass air flow sensor that is clogged with excessive carbon deposits, a vacuum leak or perhaps a fuel filter that is dirty or a fuel line that has come loose or damaged. It’s also possible that an EVAP component may have been damaged, so it would be a wise idea to have a professional mechanic come to your location and complete an on-site inspection before driving the vehicle further.
