sorry its p0303, could it also be the coil, that was the oldest and broken

Checked the obd2 codes came with a misfire in the third cylinder, I checked the coil and spark plug, they where very old and the rubber bottom was stuck to the top of the plug, got it removed eventually and ordered a new coil and plug set, hoping that would fix it. Could a bad coil and/or spark plug cause juddering when accelerating?
