SOURCE: the engine is idling high around 2500 rpm, I have

There will be a vacuum leak around the base of the throttle body gasket. You can confirm this by spraying carb cleaner around it's base. You should remove the throttle body, clean it thoroughly and replace the gasket. If you would like to really check, you can get a scan tool and monitor IAC counts. If the engine is still idling high and the counts read "0" on a warm engine, this means that the computer is trying as hard as it can to block all idle air, so it must be coming in somewhere. Possibly the throttle valve? has anyone been playing with the factory setting on the minimum idle screw?

Check for a dirty or bad Idle air control valve. (IAC) you can take most off and clean them out. It may have a lot of carbon in it and not working properly. or it could be bad also. Just clean it out first! Good-Day!

Where,exactly, is the idle air control valve on a 2004 envoy located

It should be mounted on the side of the throttle body. But if it is bad you should also have a check engine light on and a stored trouble code for the valve.

What does a p0410 code mean

Here is the definition of the code.

P0410 GMC Description An air pump is used on the vehicle to lower tail pipe emissions on start-up. The Powertrain Control Module (PCM) grounds the Air pump relay control circuit which energizes the Air pump. The PCM also grounds the Air combination valve vacuum control solenoid circuit, which energizes the Air vacuum control solenoid. Vacuum is then applied to both Air combination valve diaphragms which opens the shut off valves. The PCM enables both circuits simultaneously when Air system operations id desired. When the AIR system is active, then Air pump forces fresh air into the exhaust stream in order to accelerate catalyst operation. The AIR combination valves replace the conventional check valves. When the AIR system is inactive the shut off valves prevent air flow in either direction.
Possible causes - Faulty Vacuum hoses damaged
- Faulty Air Pump inoperative
- Air bypass solenoid harness is open or shorted
- Air bypass solenoid circuit poor electrical connection
- Air bypass solenoid leaking/blocked or stuck open/closed
- Air diverter valve leaking/blocked or stuck open/closed

Safari 1994 gmc carburator

Well the engine is fuel injected, so no carb is used.
Base idle is set at the factory, and the computer adjusts idle speed depending on load by controlling the amount of air entering the throttle body thru the idle air control valve.
