Hi I have a 2008 Nissan versa with about 140,000 miles on it, I have had multiple misfires and spark plugs replacements in the past but that was years ago. After a long overdue oil change my engine starts running too hot but I'm not sure if that's just because I never put coolant in the radiator and only in the coolant tank. And after driving it still, I had a misfire and I am not sure if it could be fixed just by adding coolant to the radiator or anything else so that I don't have to pay a million for a spark plug replacement.

A "million" to replace 4 spark plugs? Are they solid gold?
There is troubleshooting information for misfires and overheating in the FAQ. Given the symptoms you might want to check for a blown head gasket.
