I own a 2004 Hyundai tiburon and i was driving and all of a sudden the throttle just stuck on full throttle. so after it got close to redline i shut the car off. now everytime i try to start it up it is on full throttle and the RPM's go up fast. I replaced the throttle position sensor but i still have the problem.
We actually have a TSB for the drive by wire systems that calls for both a TPS sensor/actuator replacement but it's required that you also do a PCM reflash at the same time. If you put in the new updated part without doing your reflash then you've found your problem.
Take it to the dealer and get the reflash done.
I agree with pykode
Your problem lies in the throttle-cable that maybe broken, or the butterfly valve that maybe sticking due to carbon deposits in the throttle body. You could lubricate all the mechanical linkages to the throttle body. Also it would be better to remove the throttle-body and clean out its interior with a throttle-body & choke cleaner. Replace the throttle-body gasket as well.

In order for a fuel injected engine to ran way up to redline,it has to be a combination of
air
Clean Mass Air Flow senor and connector with CRC Mass Air Flow sensor or electrical part cleaner.
fuel,
Check fuel pressure at fuel rail
ECU
incorrect / grounded / damage wiring on the TPS.
Throttle cable linkage
Smooth throttle movement?
Carpet under the gas paddle (like Toyota?)
My best is a grounded and short TPS.

im not quite sure what that means.

no the gas pedal comes all the way out. and whenever i start the car up my throttle cable doesnt move on my throttle body. i figured it was the throttle position sensor and replaced it but it wasnt.
Gas pedals in those like to get stuck to the carpet if you stomp on them. Sure that isn't the issue?
is it a drive by wire
