the very first step is to check oil level... don't just ignore it... this could be simple fix... Side note how low on oil do you need to be to get a CEL?
Sometimes i hate not knowing about cars lol ima country girl and i cant work on cars i use to work on my jeep wrangler all the time.
So if i change my oil and its still jerking what should i do?
The steps that I posted above are straight out of the book, it's what a dealership will follow. Then they'll start guessing. I suggest doing as many of the steps above as you can.
