This code means that the number 1 cylinder is not firing properly, and it is misfiring. So, it may feel like the engine is running properly but unfortunately it is not.
Here are a couple of guides that will talk about this:

So, to figure out what is going on with this cylinder you will need to check the spark plug and find out what it looks like. This will help tell us what the cause is.
I am attaching a chart below that will help with this.

So let's run through this info and we can go from there.
