Spectra Premium TB1048 fuel injection throttle body for the 2008-2009 Chevrolet Impala 5.3L and other vehicles regulates the air that enters the engine. Sold as a fuel injection throttle body assembly, it opens and closes a throttle plate to set that airflow.
A rough or unsteady idle, hesitation when you accelerate or a check engine light can be signs of a dirty or failing throttle body. A vacuum leak, a dirty mass airflow sensor or worn spark plugs can also be behind those signs, so find out what is behind them before you buy a throttle body.
The vehicles it fits include the 2008-2012 Chevrolet Colorado 3.7L and the 2008-2012 GMC Canyon 3.7L, along with many others. Open the Buyer's Guide tab and look up your exact model and engine.
