So you moved your tC to Poland, awesome! I bet a lot of people have never seen that before! Actually they have but it's called the Avensis. Except no one has seen a 2 door avensis!
Ok now I understand why you're asking questions, because the mechanic in your area/country hasn't had to work on a tC before. I don't know if you get the same engine over there, the 2az-fe engine. Over here it's used in the Camry, Rav4.
Engines are the same all over the world. Fuel, air, spark. You could test the fuel pressure but I have never heard of a fuel pump that causes your kind of problem. It could be the sensors in the gas pedal (there are two, main and a backup). But I keep thinking it's the throttle body.
Here's an idea.. Open up the rubber intake tube from the throttle body throat. Have someone turn the key to the ON position, but do not start the car. have them push the gas pedal 25% down, then 50% down, then to the floor. And watch the throttle plate. See if it hesitates in its movement.
Next thing, with the tube off, have them start the car. At idle, see if the throttle plate is moving on its own without input from the gas pedal.
You can connect a scanner to the car, look at the live data. See if the TPS (throttle position sensor) % is moving on its own without touching the gas pedal. You will need to diagnose the gas pedal sensors.. I don't know what that procedure is right now.
But at least I could give you some information to help you diagnose and/or eliminate some ideas.
And thank you for explaining about your language, I was able to understand what you are saying.
