Default what are some symptoms of spark plugs going bad

My car has 78,000 miles on and I dont think its ever had a proper tune up, it has starting issues sometimes that lead me to believe its not firing correctly. Sometimes you will hear a poping sound from the exhaust rather than a correct start. Any ideas or recommendations on a type of plug?
