[Car starts abruptly when you press the gas pedal]

Hi all,

Please advise.

When I press the gas pedal, the car starts quickly (push), there is no smooth acceleration,

I stop at the STOP sign, press the gas pedal and the car starts abruptly. There is no smooth acceleration again. 🙁

What could it be, how to solve this problem? How does your Matrix behave before 2008?

Thanks
