Could you be a little more specific. Is your check eng light on? The idle is controlled by the PCM (power control module), is your idle not smooth or does the Tahoe stall? What size engine do you have? How many miles are on your Tahoe?

there is 155k miles on it, and the check engine light was on before I had this problem, but since then I had the battery go out and the light is not on any more. If I keep my foot on the gas to keep rpms above 800 or so for a while, the idle settles down and stays around 600, allowing me to drive it normally.Its a 5.3 engine.

Vehicle: 2000 - 2004 Chevrolet Tahoe 4.8L 2000 - 2004 Chevrolet Tahoe 5.3L Symptom: The engine starts and stalls or stalls on deceleration. Rough, low idle. No trouble codes. It runs normally with the accelerator pedal slightly depressed. System: Emissions/PCM/Fuel Codes: N/A Problem: Dirty throttle body Test & Fix: Remove the throttle body air boot. With the ignition OFF, key out only, use a rag soaked in cleaner and wipe out the throttle body and throttle plate. The throttle plate should move freely to allow cleaning. Some vehicles have a reflash available to address this issue.

The first response should address you problem immediately. You should really consider a complete fuel injection service. If you want to know more about what I'm telling you e-mail me at autoknowhow@gmail.com

backyard tech's answer will most likely fix your problem. i own a tahoe 5.3 which was fixed by throttle cleaning using carb cleaner from a parts store and an old toothbrush.
