Hello - first task is to retrieve whatever problem codes are tripping the Check Engine light. Most auto parts stores will do that for you for free. Without that info, I suspect you have a weak spark plug or ignition coil, or possibly a fuel injection problem. The wrong fuel mix can cause misfires as easily as ignition causes. For further diagnostic assistance, I recommend an engine misfire inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.
