the other day while i was racing some guy in a bmw m3..he said my car spit out a ball of white smoke and he thought i blew my engine,but nothing went wrong,but my engine light was on before the race but i think i need a o2 sensor...can anyone tell me what might have went wrong......

 

Keep a close eye on your coolant level, also see if any leak on HG. You can stop by at local autozone ask them to check the code for you.

 

You're going to get a lot of answers with your question some maybe wrong and some right. My best advise is take it to an Evo shop if you don't know the problem. If you take some one's advise and it's the wrong one it may end up costing you more.

 

e46 M3? did you win?

i can only assume so if he saw the smoke. lol

 

ore he djust said it to scare you ,, bad looser
