when i am driving the car starts jerking?

Hello,

There could be several factors as of why the vehicle runs rough and has low power. It could be for the engine not getting proper spark or fuel.

First you need to scan for any trouble codes. Typically if there is misfire or any issue with a sensor the check engine light will be illuminated. You will need to scan for the engine codes.

Check the spark plugs for wear and gap. If you have excessive carbon build up you could have misfire when trying to accelerate. That will make it difficult to get up to speed.
