so i was in 2nd going through a parking lot, and there is usually no cars coming in this lot, so i wasn't expecting to stop, then all the sudden i had to hit the brakes, because a car just turned and went in front of me and I forgot to push the clutch in. The car jerked back and forth for like 2 sec, never stalled....But since then the check engine light is on, the car seems to drive fine, and if I am driving it is it wrecking anything?, how do I diagnose the problem?. And where can I find a list of codes for this? The car is a 5g lude.
