Question about 2003 Hyundai Tiburon
I have a 2003 tiburon 5 speed, i currently replaced the throttle position sensor, mass air flow sensor and rebuilt my throttle body. When i turn it on it stays on 2000 rpm??? what can i do next, people tell me it might be the ecu but i dont know..
Have you tried just disconnecting the battery for a half an hour or so? Your ECU probably just needs to forget what it has learned and relearn it.

The barometric pressure (BARO)
The manifold absolute pressure (MAP)
The intake air temperature (IAT)
The engine RPM
P0121 The predicted air flow and the predicted MAP combined are outside a calibrated range for more than 3 seconds.
Inspect thoroughly for any type of leak or restriction
Air leaks at throttle body mounting area and intake manifold sealing surfaces
Throttle body for dirt, debris, and coking--Refer to Throttle Body Cleaning.
Increase the engine speed slowly to 3,000 RPM, then back to idle.
Exit from the snapshot and review the data.
Observe the Mass Air Flow (MAF) Sensor parameter frame by frame with a scan tool. The MAF sensor g/s should change smoothly and gradually as the engine speed is increased and is returned to idle.
If the MAF sensor g/s does not change smoothly and gradually as the engine speed is increased and is returned to idle, refer to DTC P0101 or P1101.
Broken throttle shaft
Any throttle body damage
If any of these conditions exist, replace the throttle body assembly.
