Why is my car shaking and I can smell the fumes

There could be any number of reasons. It sounds like the vehicle may be misfiring. This could be caused by an ignition, fuel delivery, timing, vacuum leak, sensor signaling issue, etc. I would have to diagnose the problem. If you would like to bring your vehicle to us we can definitely diagnose your problem and repair it. Feel free to call me (Scott) Schaumburg Automedics 503 Lunt Ave. Schaumburg 60193.
