Are you saying that when the car warms up, the idle goes up? Where does it idle at cold and where at warm? Did you change the throttle body? Do you have a vacuum leak?

You are trying to keep the car as loud as it is when it starts from a cold start right?

I don't think there is anything you can do about that, its all computer controlled.

yeah thats what im saying runs about 500 when i start it and it idles up to 1000 or so when it warms up so i tried to back out the idle set screw but it didnt help could the timing have something to do with it
