Title: Re: An engine misfires on cylinder #3 when cold and the compression and cylinder lea Post by: bolbol on Oct 15, 2023 Cylinder 3 misfires can be caused by many reasons from a faulty ignition system, fuel system, or internal engine failure. The most common reason for this to happen is faulty or worn-out spark plug coil packs, especially if it’s been a while since you had a tune-up.
