Hi all! I\'m trying to help out a friend of mine. She has a 2003 Matrix with the 2zz engine and it won\'t idle down, even after it\'s warmed up. When you come to a stop and push in the clutch the engine races to 4000+ RPM (seems to be getting worse; it used to be around 3000). If you mash on the accelerator it will idle down to around 1000, which I assume is normal. I have it for the weekend and told her I\'d take a look at it. Any thoughts as to what I should look for?
