Issues with ignition, probably a cylinder failing...?

[José García]

Hello misters! I'll leave this here so may be some of you have had this issue too.
Well, when starting the engine seems like to be out of time but for sure it starts so I'd say that the worst problem is that it is not stable at idle but not that much struggle, so my thoughts are that it may be something related to the coils.
Note: it runs good but during accel it feels not solid like intermitent combustion.
I'll thank you for any reply, I'm not exactly clever in mechanical issues...

Most likely you have a bad ignition coil. Does it run smoothly for a while and cut in and out like it is running on 5 cylinders?

Sometimes if you look at the engine in the dark you can see arcing or sparks at the bad coil.

You can also disconnect one coil or injector at a time until you find the one which makes no change in the way the engine is running. Then you've found the bad one.
