Filling your fuel tank will not make your car shake, unless you got some bad fuel that was contaminated with moisture.
ummh no a sensor is not strong enough to make da car shake" it could be da injectors so u would have to chek them twice.

Not likely. Normally this is caused by a tire out of balance or a bent wheel.
