Engine light coming on and car is hesitant when driving?
Engine Light usually has to do with emissions if you bring it to auto zone or advanced auto they will read the code for you as long as the light is still on they should be able to help you from there. It is possible it could be an 02 sensor but there are quite a few sensors on the engine, another one could be Mass Air Flow Sensor sometimes they could just be dirty too.
