2003 4Runner V8 Sport jerking jumping movement

Hi all,
I have 2003 4runner V8 4WD sport edition with 129,000 miles. Yesterday morning I noticed something different with the car. I was going around 30mph until I had to brake to slow down to around 20mph. But then when I accelerated I felt the car did not accelerate only the engine roaming and about 2 seconds later the car moved forward with jerking abrupt like jumping movement with thud sound.

I was concern about that random sudden jerking movement as I could have hit the car in front of me. But I thought this happened maybe because of the cold winter temperature in NYC.

So today It happened again and now after the jerking jumping when I start to accelerate, all the lights of check engine, VSC track off, VSC Check are lit-up.
The car runs normal and the jerking seems not as worse and less as before all the lights are lit-up.

This never happened before. I never do any off road and towing.
Does this ever happen to anyone of you? What causes this and how to fix it.

Thank you all in advance.

What is the engine code?
 
Dear TFJ-4runner,
I don't know the code yet since I have not brought the car to any mechanics.
