I believe you are referring to the Check Engine light. If this light is on and you are experiencing these symptoms, I would first recommend having your vehicle scanned for trouble codes with an OBD2 scanner. Once the codes are retrieved, the diagnosis of this issue can resume. Without knowing the codes my most educated guess to would be a faulty ignition coil, injector, or spark plug.
