The last couple days it seems like my 9 has no fast idle. Now, I've haven't actually gone out and tried to start it when it's cold, and it has been sitting in the warm sun in my driveway, and since I'm not sure how the DFI system determines when fast idle is necessary, I don't know whether it just knows that it's 90 degrees outside and doesn't really need to idle up at startup. It also used to suffer from the famous hot fast idle problem, where it would idle fast at startup after a short break. It hasn't been doing that either. Is this something I should be concerned about? Is there some adjustment that's outta wack? Seems to be running fine, and the FI light hasn't come on, and it starts just fine every time. I just don't want this to bike me in the @$$ when the weather cools off.
