1. It produces black smoke and unstable idling.
2. When accelerating an engine check light comes on and when I step on the brakes the engine stops.
What is the cause of that?

Black smoke is caused by excess fuel in the exhaust. Unstable idle and a flashing check engine light is caused by this as well.

Here is a guide that talks about this:

The first step is to check codes. This should tell us which cylinder is the issue. More than likely you have a faulty injector but we need to confirm this first. I would try to refrain from driving it until this is repaired because the flashing light means it is doing damage.
