Q: car surges and jolts on 2000 Hyundai Tiburon

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
when holding speed 40,50,60 mph car surges and jolts like its starving for gas. I've replaced plugs, wires, coil, fuel filter, mass air flow sensor and injectors. Still nothing. Any ideas?

I checked the code and check engine light was on before I replaced a few of the parts. Check engine light is no longer on but still jolts and surges.
