Most of the time easy solution. Typically wrong plugs, bad or wrong coils, and low octane fuel.

how old are your plugs and what is the make / part number of them.

If over 50k miles on the coils or if not oem then buy 4 new oem coils.

If over 50k miles on the plugs or not running oem NGK plugs for a 16+ VT with .028" gaps on the oem tune then buy 4 new plugs mentioned.

Be sure electrical connections and power supplies are all good.

Clear codes and see what happens.

Be worth what I suggested considering the mileage, parts on the car, age, and the misfires.

And only use what I told you and nothing else. If you're having to pay more than $280 for the plugs and coils shipped reach out to me.
