If you are unsure, or if you find that the vehicle is operating abnormally after replacement (such as unstable idling, weak acceleration, etc.), it is recommended to contact a professional auto mechanic to check and confirm whether further calibration is needed Rainier 2004-2007 Cts 2004-2005 Deville 2000-2005 Eldorado 2000-2002 Escalade 2002-2006 Seville 2000-2004 Avalanche 1500 2002-2006 Avalanche 2500 2002-2006 C3500 Pickup 2001-2002 Corvette 2001-2007 Lcf 2016-2017 Silverado 1500 1999-2006 Silverado 1500 Classic 2007 Silverado 2500 1999-2006 Silverado 2500 Classic 2007 Silverado 3500 2001-2006 Silverado 3500 Classic 2007 Ssr 2003-2006 Suburban 1500 2000-2006 Suburban 2500 2000-2006 Tahoe 2000-2006 Trailblazer 2003-2009 C3500 Pickup 2001-2002 Envoy 2003-2009 Sierra 1500 1999-2006 Sierra 1500 Classic 2007 Sierra 2500 1999-2006 Sierra 2500 Classic 2007 Sierra 3500 2001-2006 Sierra 3500 Classic 2007 Yukon 2000-2006 Yukon Xl 1500 2000-2006 Yukon Xl 2500 2000-2006 H2 2003-2009 Ascender 2003-2006 Aurora 2001-2003 Bonneville 2004-2005 Gto 2005-2006 9-7X 2005-2009
