Hello,

It sounds like you have an ignition coil that is not working or you have a fouled spark plug. Lets start by reading the codes to see what come up.

Here is a guide to check the ignition coils as well.

I did what you said but it is not helping? I looks through the guiders and the coils seem to be working okay but one plug is black? #3 cylinder?

This is because the cylinder probably has low compression due to a burnt valve. Please follow this guide to confirm the issue.
