Ok, so my 2004 RX8 is stuck with a check engine light on. I asked the dealership i bought it from what the problem is, and they hooked up and said it was probably because someone ran it completely out of gas and that's the reason the light was on. But the next day after it was reset, the light came on AGAIN. So i checked online and people say that it could be a the gas cap and to restart the car 10 times after tightening it. I did that and still the light is on. Also, the car sometimes starts and white smoke comes out and a leak from the exhaust. I live in Colorado so it can possibly be condensation and vapor because it's cold, but could it be something else? THanks in advance!

 

We're going to need the actual CEL code. That is if you want a any real support

 

no code, no talk.

 

How do I get that? Can i do it myself? Sorry I'm kinda new to this car.

or go to Autozone have it pulled for free.
