Toyota issue

[Noma]

Hi. I need help with my Toyota yaris 2007. I've been driving it for 4yrs now bt all of a sudden the car started to idle very bad and jaggs. Losses power when I'm driving , when i press the accelerator it jst doest move instead it's like the accelerator is not working its loose or something . The dealer made me change the petrol pump but the car still do the same. Someone told me to have a look at the throttle but I'm not sure anymore because when i take the car to be diagnosed they can't find anyfault

Please advice
