New Fuel Injector from 1AAuto.com http://1aau.to/ia/1AFIN00130

This video shows you how to install new fuel injectors in your 2002-2009 Chevrolet Trailblazer (4.2L L6). Fuel injectors are computer controlled spray nozzles that deliver fuel to your engine in precisely controlled volumes. They are one of the keys to modern efficient and clean engines. If a fuel injector is dirty or failing, it can present symptoms such as rough idle, engine surges, rich or lean conditions, and check engine lights. Replacing a problematic fuel injector with an engineered to fit TRQ replacement part right away is essential to the health of your vehicle’s engine.

This repair was done on a 2007 Chevrolet Trailblazer LT 4.2L Sport Utility 4-Door 4WD Automatic and the process should be similar on the following vehicles:
2002 Chevrolet Trailblazer
2003 Chevrolet Trailblazer
2004 Chevrolet Trailblazer

2006 Chevrolet Trailblazer
2007 Chevrolet Trailblazer
