Hi, welcome to Just Answer. I'm Ron and I will be helping you today.
The fuel smell can be from a leaky injector externally, and fuel line leaking to or from the fuel rail where the injectors are housed or an EVAP hose cracked or disconnected from the purge valve.
So look under the hood real close for any of these issues and get back to me if needed.
As for the vibration, that could be tire balance.
