That's my next thing to check

Someone asked if there was oil in the distributor, i'll check for that!

I will change the cap and rotor then i might change the distributor if i have to!

Anyone else?

a way to check is
shut off the car after it appears, wait like 20-30 seconds

I tried one time to shut the engine just after a misfire, i did wait like 40 seconds and the misfire stopped for 2 minutes, but another time i tried it and it was still misfiring right after so i don't know.

I used to have the exact same issues with my vehicle. Turns out the cap and rotor were fried.
