i called the dealer and they told me that a new egr would cost 320.00. i just want to take it off and clean it does anyone know where its at. adn maybe give me some advice.
2003 will either be a 3.4L (Base model) or the 3.8L engine and slightly different than any of the 8th gen series engines. I had a 3.4L 2001 Impala with CEL on and I never did do the swap as the gas mileage was acceptable and it passed inspection without doing it. There is a discussion I found on the particular error code I had and removing and cleaning for the 7th gen engine.good thread - thanks - I know it's old - but it confirms what I was told by our mechanic for our kids 2003 Impala about the check-engine-light. I changed one of these on an older 4Runner once and it was no big deal - but this one seems to be a different animal. the drag is our mechanic said he would replace it, then we have to drive it around for a few days, then he has to re-scan it and then take it for an inspection
