Hi dan/cila and welcome to 2carpros

Remove the rear seat cushion and the access panel. Relieve the fuel system pressure by disconnecting the fuel pump module connector, then starting the engine and letting it run until it stalls. Turn the ignition off.

Step2 Disconnect the negative battery cable. Then, attach the fuel pump harness connector. Locate the fuel filter underneath the Sonata near the fuel tank. Disconnect the fuel supply and pressure lines. Remove the fuel filter bracket if your model has one, and then remove the fuel filter.

Step3 Install the new fuel filter and torque the mounting bolts to 18 to 25 ft-lbs. Replace the fuel filter bracket, if applicable, and then reattach the fuel supply and fuel pressure lines.

Step4 Reattach the negative battery cable. Start the engine of your Hyundai Sonata, check for leaks, and fix any you find.

The fuel filter is on the driver side of fuel tank, mounted on frame in fuel line. As far as the engine, check for vacuum leaks, check to make sure the catalytic converter isn't plugged and check fuel pump pressure. Also, the idle issue may be the IAC, idle air control valve.

The filter is on the driver's side near the fuel tank. It is mounted on the floor boards under the vehicle. It may be plugged or your fuel gauge may be off. If the car runs good at other times, I would say the pump is good.
