Sounds like you have a engine misfire in one of your cylinder's. So one or possibly multiple cylinders are not running correctly.

Hello,

You will need to pull codes to to determine the possibilities. Here is how to pull codes.

PROCEDURE:
When the Check Engine warning light has been reported on, turn the ignition on, move the front passenger seat to the rear position and observe the LED on the front of the ECU. The LED indicates a system failure code by blinking frequency. The ECU LED can indicate any number of simultaneous component problems by blinking separate codes, one after another.
