2000 RPM at startup

[20GMC00]

I have a 1999 Ford Explorer Sport 4X4 Sport 4.0 OHC that idles at 2000 rpm or sometimes a little higher every time I start it. It doesnt matter if the engine is warm or cold. It idles that high for about 4 or 5 seconds and I really dont think it is good on things to start at that speed. Any ideas? Thanks.

I think that high an idle speed is a little excessive, especially when warm, possible cleaning the Idle Air Solenoid, the Throttle Body, Mass Airflow Sensor and the Intake Air Sensor. If that doesn't help, I would guess it is in the Computer. This is what I would do. These electronic marvels sometimes are a real PIA to figure out.
