Finally read this thread....great job finding and fixing the problem!

Nice job, sometimes it takes a while to find the gremlin.
Congrats on the fix. Isn't it funny how when you find a problem and fix it, you actually feel BETTER than you would have if you'd never had the problem in the first place?![]()
I had a similar "triumph" early this month, though mine wasn't as troublesome. My '04 Suburban started throwing a CEL just before our big Thanksgiving trip to Texas. Fortunately I have a Scangauge so I was able to read the code and look it up - it was a P0161, right downstream 02 sensor. I reset it and kept going (the truck ran fine) but it would annoyingly come on every time I started up again.
I was all resigned to take it to a shop when I posted my issue on the Tahoe/Yukon forum and they said "Dude! It's an easy fix!" So I watched a YouTube video and sure enough, the sensor was on the exhaust below the cat (I had thought it was somewhere on the engine that would require me to take a lot of engine parts off in order to access it.) Bought a $45 sensor (with a $20 rebate) at Vato Zone, pulled the truck into the garage and swapped the sensor out in literally 20 minutes - and 10 minutes of that was me figuring out how to position the truck and how to jack it up so I could get under there with the creeper (yes, it was on jackstands!)
Even though it was an easy (and cheap!) fix I felt good knowing that I was able to do it myself.
It's also good to see that people are getting over 200k out of these GMT-800 trucks. Mine just turned over 180,000 and although I've been toying with the idea of getting a new(er) truck, the cost just pisses me off (not just the cost to buy but the exorbitant sales tax, registration fees and insurance on a newer vehicle.) So I've decided to keep the 'Burb for another year. If I drive about as much as I did in 2018 it should be right around 194,000 by December of next year and then I can decide whether I want to bite the bullet or try to keep the old gal running for another camping season.

If you love your freedom, thank a veteran. If you love to party, thank the Beastie Boys. They fought for that right.
The best thing about doing any kind of repair work yourself. Is knowing you had it buttoned up a day before your chiro, or massage, appointment.

More than likely because most people don't know that the factory harness for trailer brake controllers are stuffed up in the dash. He probably just assumed he was an electrician and everything has to be wired!
Just met with a member on a 40 min test drive and no lights! I'm stoked! In celebration, I am taking the girl to a paint and wine class and guess which vehicle we are taking?!
The Tahoe. We are taking the Tahoe because women are always right.
