The check engine light on should set a fault code in the system. That should be checked to find out which direction to take. You can have an ignition misfire due to a bad coil or even worn spark plugs. There can also be a fuel system issue. One or more injectors may be clogged or failing. Improper spark or incorrect amounts of fuel can cause misfiring, sputtering, low power, and even hard starting. On a cold start, the engine needs more fuel to start and run smoothly for the first few minutes.
