could be due to dirty fuel injectors...

I agree with @onikka

Dirty fuel injectors are among the most common reasons for why an accelerator becomes jerky. The dirty injector leads to your car losing power when you attempt to accelerate while at a stop and when you try to drive at a consistent speed. This is the result of an engine misfire.

There could have been blockages too...that is preventing your car from receiving the fuel it needs to accelerate. Air mixes with fuel to create a spray that powers your engine. If anything interrupts this, your car might struggle to accelerate

could be because of worn out spark plugs too. Your spark plugs might be worn out and unable to properly ignite the fuel in the piston fast enough. This can lead to your car not accelerating as quickly. Fortunately, spark plugs are not expensive to repair and replace...haha

Above are all the possibilities as to why your engine jerks. I heard that Petronas most recent petrol has got 100 times cleaning power to deliver perfect cleanliness. Maybe your wife can try to pump this petrol to see if it helps.

I have experienced the same problem. First of all, replaced the spark plugs and everything will be OK again. But u need send ur car to workshop to check the main problem.

yea, of course. First need to send to the workshop for inspection then do necessary repairs. After that, find a good solution to maintain the condition of your car fuel system in the long run so that lesser and lesser of such things to happen in the future.
