In this video I'm still trying to diagnose and fix a rough-idle issue I'm having with my 2005 GMC Envoy 4.2L Vortec. I've replaced a bunch of parts and the problem persists.

Today, I've decided to rule out a couple of things. The first is the compression. In previous videos there've been a lot of comments about doing a compression test. In this video, I finally perform that compression test. Secondly, I wanted to rule out the spark plugs. They are an easy enough fix and relatively affordable. Unfortunately, I didn't realize, until I started doing a little research, that there are possibilities of non-genuine ACDelco Iridium plugs out there. So, that led me down a bit of a rabbit hole but I'm pretty sure I've gotten it figured out.

Enjoy.
