You should have it scanned, hopefully you or one of your friends has a scan tool that will read live data, even without a code set there maybe a sensor out of range that can cause the problem. I agree the spark plug that you havent changed could be part of the problem, but usually it will miss at all rpm , not just midrange. And a scan will keep you from throwing alot of parts you dont need on it. good luck
