car runs bad when I give it gas but check engine light is not coming on

I recommend a professional diagnosis with a good scan tool. Even though there isn't a code they can look at live data to determine if a sensor is causing the car to act up. Here is a link to find a shop near you. https://repairpal.com/repair-shops Alex
