Give a better description of your problem.

Not sure if it is your auto correct that is changing words, or a poor translation to English.

My guess is “jerking while driving at a steady speed”, is your symptom, correct?
First—Is the check engine light on? If so have the codes read and post them here. Format will be P0123.

Jerking could also be a symptom of a transmission problem.
