Ive had exhaust on my car since Ive had 1000 miles and I now have 20k I dont think its the exhaust.

 

Of course the code comes on every time you start the car. If you do not remove the code or reset the ecu the code will stay on. The code is most likely P0420 which is the catalyst thing that is happening to most. You are fine don't worry about. The only thing with the cel code is the annoyance factor if it is the p0420. Your car should be fine!

 

God damnit this better not be some gay misfire code I cant get rid of, Im gonna try autozone tomorrow.

 

So they said it was bad gas and charged me 88 bucks!!!!
