How do faulty spark plugs affect Mini Cooper performance in Pakistan?

My Mini Cooper is misfiring occasionally, has rough idling, and sometimes struggles to accelerate. Could worn o r damaged spark plugs be the reason? How can I check the spark plugs for problems, and what are the best solutions considering the fuel and driving conditions in Pakistan?
