I love working on 3.8s best engine ever made. How's your macular degen by the way? Has it improved on carnivore. I also have some optic nerve damage and vitamin b3 3 grams a day + ketovore is reversing it.

[@frugalprepper]

It has improved a little, but not much, but it has stopped getting any worse.

G'day Tom , Yay Team ! Good stuff mate... Yesterday I posted a Video you might get a giggle from...(?), "Nandy's Shooting Box...!" Back in 1939 my big sister couldn't get closer to "Grandpa" than "Nandy", and she was my Grandfather's first Grandchild, so that became his Name...! I was his last-born grandkid though, so I wound up with some of his Tools the walking-stick, Guns, and the Shooting-Box. Which I finally had a Locksmith open up for me After having lost the key 25 years ago. So I reveal a sheaf of old .22 Targets dating to my 1976 Rifle Club dayze at Boarding School, and my Hundred year-old Target-Shooting Elbow Cups (!). Have you ever seen a set of them ? Wonderful bits of gear, but I've never yet met anybody else who even knew what they're for. Forgotten technology ! And, then, I show off a certain Bent Stick As a Movie-Prop., While demonstrating the Box's Secret Cunning Actual Purpose, When lying Down on the Mound - with the Elbow-Cups doing their Thing. Now I can take the Doors and fittings off and sand it all back and refurbish it with Danish Oil... Such is life, Have a good one... Stay safe. ;- Ciao !

I had a problem with misfire at higher rpm on a 6.2 escalade it ended up being a bad ground.

[@frugalprepper]

Those Yukon's and Escalades have bad grounds galore!

[@oldriver1827]

When ever I see a coil or ICM failure the repair includes checking, cleaning engine ground. New components might handle a weak ground but will be stressed to fail sooner.

[@colinschmitz8297]

Are new ac Delco or Delphi units worth anything or are they also cheaply made junk?

[@frugalprepper]

I don't know. I just get mine from the junk yard.

[@wendwllhickey6426]

Middle one is the one that goes bad most of time😂

[@lightcapmath2777]

If a waste spark occurs during the exhaust on another cylinder, would that not help in some ways to burn off hydrocarbons? HxCy DVD:)

[@frugalprepper]

No, there is nothing left that is burnable by a spark. That is what the Catalytic converter is for. Plus it fires at the top of the stroke, after it has pushed all the exhaust out.

[@lightcapmath2777]

@@frugalprepper Understood, so just a waste in the lifespan of the coil...ummm thanks DVD:)

[@frugalprepper]

Not really it is just one coil with two outputs. It may shorten the life, but not all that much. It's a common problem I have seen before, but the 3.8L GM motor is the most produced motor in the entire history of automobiles.
