Okay to say the least, I've never actually raced before. I was racing a 3000GT VR4 we were nose and nose. I was in 5th going like 110-120 at 6 grand and my car made like a jolt. Then a check engine light popped up for not even a half second. I didn't even have time to see it was there. I've never run the car hard before this and it only has 52k on it. My buddy told me that it was just "breaking it in" since it's never been run hard before. I hope nothing is broke or wrong with it. It acted completely fine after I slowed down and was driving normal.
