Engine light (with the lightning bolt).

What is your question?

My car's engine light (with the lightning bolt) came on while I was driving it. I had noticed the car would sometime jerk at high speeds. It was like the engine shifting gears but I was doing 60 mph. Does anyone have any ideas? I live in Hawaii and they don't do free inspections here. I would have to pay 160.00 to have someone read the code. I also noticed that the oil was very low when I checked it.
