I have a Protege5. Awhile back while I was changing the ignition coils it came to me that...How can there be only 2 ignition coils?
Since this is a 4 cylinder engine, each cylinder should be fired 180 degree apart. If two spark plugs are controlled by the same ignition coil, then it should be fired together? That means although this is a 4 cylinder engine, we really only have a 2 cylinder engine in terms of balance and smoothness.
Actually even the service manual says that "Note
No.1 and No.4 cylinders and No.2 and No.3
cylinder are ignited simultaneously."
This is so stupid...how can Mazda design something like this? That's why we have such soft engine mounts and still the engine is shaky and loud...
