Question about Hyundai Sonata
Have you try moving the throttle by hand to see if it is sticky??
Another thing that can make the TPS act crayzy is the IAC solenoid.
Unplug electrical connector and remove the two IAC fastening screws, remove IAC solenoid, using a rag wet with fuel injector fluid, wipe the solenoid body clean. wrap the rag around a pen or pencil, spray some cleaner and insert it into the solenoid's housing, make sure to wipe clean the far end, where the solenoid sits. Make sure not to scratch the housing walls. DO NOT SPRAY FUEL INJECTOR CLEANER STRAIGHT INTO SOLENOID BODY OR HOUSING.
Retract solenoid by grabbing it by the cup and turn back and forth while you push in. Do not push too hard. Reinstall solenoid and fastening screws, Plug electrical connector. Start vehicle.
The building of carbon on the seat and tip of the solenoid will prevent it to have a tight seal, therefore a rough idle and a problem shifting.

Hello! Lets check the TPS with a volt meter...Using two safety pins...Push one pin into the rear of the in-place connector on connector pin #2...the other into pin #3...Set meter to read 5 volts...Place + meter probe on pin #3...The - probe on pin #2...Start engine...At idle, meter must read less than 1 volt (.85)...Slowly increase throttle to full...meter must read 4 volts...The issue is this; Voltage must rise smoothly as rpm's increase...If the voltage jumps, skips or acts erratic the TPS is defective...Send results...This test establishes a starting point....Guru............Saailer
