If it’s only on cylinders 2 & 3, then it must be one of the components in those cylinders. Have you replaced the spark plugs, yet? I didn’t see those in your list, and that’s where I would have started.
I agree with chaissos. Make sure you have OEM spark plugs installed and, if this model has a distributor, an OEM cap and rotor. If any of these parts is aftermarket it can cause trouble. You did not mention the age of your spark plug wires but if they are old or they are aftermarket you should replace them with OEM wires. Japanese cars are especially fussy about aftermarket changes to ignition systems.
new plugs new wires
