Hello,

It sounds like the issue could be a faulty ignition coil or the ignition control module. It could a bad connection from the coil to the wire as well.
So do a thorough inspection for any corrosion or debris.

I have attached the diagram that shows which is the coil for the cylinder number 3.

Please let me know of any questions.
Thank you.
