most big box repair stores like Autozone will loan you an OBD2 reader or you can buy a basic unit for about $30 at Harbor Freight. there's a port under the dash (usually on the drivers side). plug the reader into the port, turn the key to position 2 (ie dash lights go on but car is off - lol if you had a dash light...) and then follow the prompts on the reader. Typically coils are reported as misfire codes like P0301 is a misfire on cylinder 1. P0300 is a generic code 302 is cylinder 2 etc. Once you see a specific cylinder misfire, next step is to swap coils with an adjacent cylinder to see if the misfire moves with the coil. No need to replace all the coils, just the bad one (assuming that's the cause). Sometimes spark plugs or fuel pressure issus can also cause misfires but those won't move when you swap coils.
