This video is an in-depth tutorial of replacing and inspecting fuel injectors on a Wrangler JK with the 3.8L motor. This applies to all JK's 2007 through and including 2011.

This is the first of a two-part series, the follow up video, replacing the fuel pump assembly can be found here:    • Wrangler JK Fuel Pump Replacement  

UPDATE 10/17/2020: I finally got around to completely replacing all 6 injectors. I used the MOPAR branded injectors, 4861667AA. The codes are GONE. If you are replacing injectors, do NOT use Bosch 0280158119, which is what the previous owner installed.
