My IAC valve is mounted by hoses, looks nothing like the one in the above photos. They're not all the same. Put the stock intake on already though.

Well it sounds like my car is running like it should then. It's the design of the car to idle at 1500 until you come to a complete stop, then it goes down to 900rpm or so, like it should. So I don't think there's a problem. Why are you saying to put the stock intake back on then?



I filled up last night and got 33mpg this time! That's a huge gain...I'm thinking it's because the ecu finally reset itself. No way am I going back to stock if I'm getting way better mileage! I don't care if there was a power gain or not.
