Do you have to replace all spark plugs (depending on how many plugs there are) even if one or two of them went out?
I would, for the sake of even combustion across all cylinders and because if one or two are bad the others will probably not be far behind.
I always change them all out together.
They’re so cheap for most cars these days, why would you want to guess (with the other plugs) when diagnosing a problem?
Change all and move on! If ones bad others can possibly start acting up. Again it all about age and mileage
