Searching for the fault to get some clues on my weird results I found one of his videos on that exact truck with the same problem. Apparently another shop had it and was doing the same dumb thing i did and forgetting how the system operates to allow for a fault check which was giving me results I didn't expect. He was even like I bet I know what they did, called up the shop and explained the problem in testing it the way it was. I like that he seems to get a lot of problem cars from other shops (another thing I'm trying to expand into) and he has a good attitude about it doesn't mock them or anything from what I have seen.
Even finally broke down and bought a pico scope the other day partially because of his videos.. but mostly because I have wanted one
