if you car shakes when its fully stopped it may be the harmonic balancer, take it to a garage. is it shakes only when you are braking while stopping than have you brakes checked
To calculate how far the car travels while accelerating, you would need to use the kinematic equation: distance = (initial velocity × time) + (0.5 × acceleration × time^2). Plug in the values of the initial velocity, final velocity, and acceleration into the formula to find the distance traveled.
A gas leak with the car sputtering while accelerating could be a hole in the vacuum hose that controls the flow of gasoline out of the tank. This type of leak is usually not caused by the fuel pump itself.
