    The other possible causes of a misfire in your cylinder #5 aside from what you’ve mention are defective spark plug wires, defective oxygen sensor/s, burned exhaust valve, and defective catalytic converter poor compression. Check the condition of your spark plug wire in your cylinder #5 and if it’s in good condition perform a compression test if possible to know the condition of your engine.
