What did you do to your NNBS GMT900 Tahoe/Yukon Today?

Smart ..still running my factory pieces...200,000mi

That is a crazy long time for the originals.
When I swapped mine, they looked like they were very brittle and one had a slight leak that never hit the ground, but I did find some corrosion on the coil pack just under the T connectors and the coolant did need to be topped off every few months.
Zero coolant loss since they have been replaced.

if anyone is looking for your basic throw in the glove box obd scanner, this one doesn't show up very often but is unique in my eyes because it reads the code and gives a description.
instead of just p0300..... it is p0300 random misfire, so you don't have to turn around and have to go look up what the code means.
cheap $25 I don't think it does abs/srs but I could be wrong, it might do abs but it is unclear I have one but haven't had a abs code in forever.

Gone.

But, I have gifted similar, small scanners to people that needed them.
Made them happy and I didn't need to lend out my expensive scanner and worry about something happening to it.

I have that one that I keep in the center console even though I don't need it because I have a reader built into the radio, but its useful for helping other people out randomly.
it's the only cheap little one with a backlight lcd, gives the code and the definition that I have seen even though it's a harbor freight special, I don't think their newer ones do the same thing.

I have a bad habit of carrying around my expensive scanner just in case I need to help someone.
I want to upgrade to a newer one so I can be less worried about this one but it really does everything I need for an OBDII scanner.

What I should really do is invest in an HP Tuners setup or a Tech II.

I have HP Tuners. Wish I knew how to use it for more than turning off vats and rear o2 sensors.

what do you want to do with it?

there's literally a youtube video dedicated to almost everything and even a few guys that patreon accounts what will help you one on one.

you just need a clear goal and the time to learn

Yeah. Tons of vids for sure and I have watched many. I know fix air first then work on fuel, but I'm just not putting two and two together on what to change and how much to change.
Goat Rope garage has some great videos I need to watch again I guess. Been at least a year since I used it.
I think it's a case of teaching old dogs new tricks in my case.
