do i just take the spark plug out of the cylinder socket...and put it in the wire, fire the engine to check for spark?

trying to isolate a miss on the CE. Don't know if its fuel injector related...spark ..or vacuum.

seems like cylinder 3 is the culprit...but i want to confirm that the plug is ok before exchanging fuel injectors.
