Fit 09 Chevy Tahoe 5.3

After installation, the idle speed was 35k. I tried restarting the computer, tried letting the computer relearn and tried controlling it, but the idle was still high. I had to take it to a mechanic to have it calibrated. After that it works great.

Pros

The throttle body is the throttle body that is located between the intake air filter and the intake manifold. When the driver presses the accelerator pedal, the valve opens and lets air into the engine. As more air enters the engine, more fuel is injected, increasing performance. A properly sized throttle body provides adequate airflow and velocity for good engine performance and throttle response.
