e420x, If your reffering to when you bring your car in after running it hard for a while, that it still idles high for a few seconds, that is okay. ideally it should idle high for about 4-7 seconds once brought in. Than it should settle. You could richen the bottom end up a bit, but you dont need to. Another good thing to do is, get the motor up to operating temperature. bring it in, Pinch the fuel line right at the HSN needle. Count how many seconds it takes for it to die. It should be about 5 seconds give or take a few. If it runs for longer than that rough area, than lean it. if less, richen it.
