What causes the BMW 328 to shake and stall during cold starts?

[AlanaFitz]

The reason why the BMW 328 shakes and stalls during cold starts is due to excessive carbon deposits. Carbon deposits can accumulate on the inner walls of the throttle body, the intake valve heads, the inner walls of the intake manifold, the top of the pistons, and the inner walls of the combustion chamber. Taking the 2016 BMW 328 as an example, it belongs to the mid-size car category with the following dimensions: length 4753mm, width 1811mm, height 1455mm, wheelbase 2920mm, fuel tank capacity 60l, and curb weight 1590kg. The 2016 BMW 328 features a double-joint spring strut front suspension and a multi-link independent rear suspension. It is equipped with a 2.0l turbocharged engine producing a maximum horsepower of 245ps, maximum power of 180kw, and maximum torque of 350nm, paired with an 8-speed automatic transmission.
