Idle rough then boggs down like starving for gas where is fuel pump on 2000 Hyundai Tiburon

Replaced Throttel position sensor,mass air flow sensor and idle control valve ran good for a day. Problem started with high idle then boggs down like starving for gas.Should i change injecters ,fuel filter, and pump. Check engine lite is on

The best move is to have the engine codes pulled from the Engine Control Module. This will give you clues to get a diagnosis going. Don't spend any more money on parts until you have a good, clear direction!
Thanks, I replaced the fuel tank gas cap and sprayed carburator cleaner forward of the mass air sensor. I than put Injector cleaner in fuel tank and used premium gas now it runs great. Thank you for your input. The check engine lite went out also. Runfast.
