Hello, so I have a 2006 kia spectra5. The check engine light has been on but I assumed it was just from changing out the alternator. Well today when I merged onto the highway there was a click and the car wouldnt accelerate anymore, the car was running, the engine revved when I pressed the pedal. Then when I had turned the car off and went to restart it it wouldnt turn back over although it sounds like it could. If you know what this could be please explain.
