It turns out I need a new MAP sensor. So I went on ebay and bought 1. The seller said it fits 1998-2003 2.7L Intrepids. I have a 2004 Intrepid so he said it wouldn't fit. As far as I know, the 2004 engines are the same as 1998-2003s, right? Also the Haynes Repair Guides have 1998-2003 editions and also 1998-2004 editions.. So I'm confused!
