Looks like you have a carbon deposit issue on your cylinder heads. there are two ways you can tackle this issue. you can perform sergury and remove the carbon deposits yourself either on the cylinder heads or inside the cylinders themselves. if you cannon do it, your nearby mechanic should be able to.
or you can improve the quality of gas you have in your tank by upgrading to a higher fuel grade (preferably octane 93). in addition to that you also should also add fuel additives to remove any water deposits which may also cause missfiring. after going through a couple of tanks like that you should see some improvement.
i used to have an old 92 stealth that missfired everytime i switched to a lower grade fuel after a couple of tanks. whenever i upgraded the fuel and added additives, after a couple of tanks it missfired no more. worked for me.
