I have had a check engine light on for the past few months and I finally got around to getting it to AutoZone to have it read today. They claime its the EGR valve throwing the code. I would love to just take this off and clean it with carb cleaner and a toothbrush and then replace using a new gasket BUT, how hard is it to get the EGR valve off. I know its under the throttle body but wasn't sure if this is the only way to clean it or if I can run seafoam through the gas and oil a couple times and that would work? One other thing bothering me about the read is that the autozone didnt have an actual set of hyundai codes so he used a mitsu code which he claims will be the same with this type of error. I did see a Kia section though so i went by that.
Sorry for the book but wanted to be as thorough as possible. BTW this is a 04 GL with a 2.4 A/T 73K.
