Hi I'm a new owner of 03 is300 I'm trying to figure out how to take care of my car. Pretty much my daughter did not service her car very well so now I'm doing it for me! I get more excited the more learn about my beautiful Blackwidow. Now she's not passing emission test lights are on I feel like I'm going in circles may I please get some helpful information/teaching on my babygirl!

 

does it have any mil codes? if so, what are they?
