Hey my Cruiser was originally showing a misfire on cylinder 2 and 3. Now it is showing 2, 3, 5, and 6. It is running and the oil looks fine. Any idea what range of issues this would be? I replace the coils and plugs with OEM parts about 6 months. Worried it is the head gasket.
Any help would be great!
Thanks

1 bad coil can start to fool the system into thinking there are multiple bad cylinders. A misfire can initially show the bad cylinder, then quickly migrate to many others. You could just have a bad coil or plug with infant mortality. Did you save any of your original coils as spares? I'd swap out one at a time and see if it makes a difference.
Pick one misfire cylinder and one cylinder with no code and swap the coils and plugs between them. See if the code follows. If it does, it's a plug/coil issue. If not, check resistance on injectors and do a compression test.
