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

2003 Chevrolet Trailblazer
2004 Chevrolet Trailblazer

Amazing! Love these videos. I love to work on my own and these have helped so much. Thanks for making them!!
You should mention to your viewers, you will have to relearn the idle.... other than that,good job on the tutorial. 👍👍
No grease on the o ring??
Does the 2003 GMC Envoy SLT have the exact same parts and placement of the fuel injectors as this video? I have this particular Envoy and noticed that the top area looks exactly the same. So I'm wondering as you go deeper to the fuel injectors, are the parts and placement exactly the same.
I bought one the guy just replaced the fuel injectors and said it never ran good again he said it was missing on two cylinders or there is air in the lines but it does run but is really rough any suggestions
Since you unplugged the negative terminal and had to remove the throttle body, do you have to do a relearn process on the throttle body?
Thanks! Very helpful.
Such good videos
