Question type: Maintenance & Repair

I'm getting a misfire #4 cylinder. The plugs and wires have been changed. I've
tried switching from the number 3 to the number 4 but it didn't change
anything. What could the problem be?

if it still doesn't help, then do a cylinder pressure test. the valve on the cylinder might be a problem.
