Scan the vehicle for any codes it may be throwing. They are stored in the ECU even if the CEL isn't lit up currently. Did you or a shop replace the gasket? If you didn't have the head resurfaced and torque the head in sequence and use new head bolts, there's a possibility it didn't seal. You can do a compression or leakdown test to confirm this. Also, ensure you have the correct plugs and they are gapped to the correct gap for your car.

It was a shop i took it back to same shop and he said it misfired because he didn't clear the ECU. He cleared and misfired again the next day
