Define misfire when you get on the power too hard. Does this mean it sounded like it misfired to you or was there actual data of some sort that said that it misfires under too much power?Cars no longer throwing the misfire code. Only misfires when I get on the power too hard. Gonna have the valves cleaned tomorrow and see if that helps. Also I checked the plug gap and I do run 91 octane. Good idea to check the coils at the terminals though, so ill do that.
Checked the plug gap does not say that the gaps were .028". Nor does that say the plugs are heat range 8. That more says that neither are or were those specs.
Hope you get the valves walnut blasted and not a chemical clean through induction like most do. Induction chemical cleaning is not safe in many cases especially in many of these cars.
Keep in mind on the coils that checking the resistance even per the FSM may not help. By this I mean that you can't actually test the coils properly to know 100% if good or not without disassembling the coil itself and doing such would leave it inoperable. Best bet is replacing if you know or suspect they have 50k+ miles on them.
