Car starts abruptly when you press the gas pedal

Recommended Posts

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

Throttle position sensor. Did you recently clean the engine, specifically near the throttle body plate and intake? If so, you will likely need to recalibrate the sensor. 

Another issue you may have is worn out spark plugs and maybe cool packs. 

Also a dirty iacv can have the same symptoms you have.

The last item maybe dirty or clogged fuel filter.
