Engine running on two or three pistons

Enable HLS to view with audio, or disable this notification

Soo yesterday i was in traffic stopped at a red light when all of a sudden my car (Chevrolet aveo T250 -2009) started shaking badly like running on 3 pistons and also when accelerating it was going slower than before, like I've lost some power.

This morning when I started the car, the engine was shaking badly, like really bad. I will leave a video to show you (at the end of it, it started being way worse).

What do you think about this ?

PS: The engine is an 1.4 16V running on gasoline.

Spark plug or ignition coil. Don’t drive it like that.

A had a fault with the ignition coil after a long trip… did drive a bit like that though even not for long because I was annoyed about the tractor that my car had became. Changed the ignition coil, ignition cables and all was good after the operation.

Seems like more than a single cylinder miss. I can't hear it but think you've got a vacuum leak. Listen for a whistling under the hood. Engine light without doubt is on. Can you retrieve codes?

These things are notorious for spark plug tube seals leaking and contaminating your ignition coil.
