Remove battery cable, reattach first step.
Usually a misfire.
You should ensure that you have had any needed repairs done to your vehicle when the check engine light comes on. If you have an ODB reader and already performed the repairs, you can use it to reset the check engine light, otherwise it can take time after a series of cold starts, and a mix of city and highway driving for the system to reset itself.
To reset the check engine light you must have an OBDII code reader with the reset function. The underlying fault that caused the light to turn on must be fixed or the light will turn on again once the condition is detected. The light will be reset if the battery is disconnected for about 10 minutes but will turn on again if the fault that caused the light to turn on is not fixed. Also, the engine will not run at its best until the computer is retrained.
