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

[Rocket Man]

I don't know man I stole a straight 6 maxima once, 5 speed, that thing cruised like butter at 140 and had lots more to go, kinda want to get a legit one someday but there isn't many around in fact there almost impossible to find.

But they’re UGLY. And a Datsun to boot.

Changed 7 out of 8 plugs today. Ran out of time to get to number 8. Thats gonna be a absolute pain in the ass. I cant wait!! Driver side plugs looked like crap. Its also the side im getting some sort of noise on...fearing its the lifter failure. Passenger side plugs all looked decent enough for 90k, but definitely time to go. After plugs, the noise seems to be less and only when revving down towards idle. its kinda hard to hear at times. E85 also seems to have helped with it.

The few times I’ve rented it’s always been Chevys.

I always get full-size suv or premium suv. Yukon's mostly. Had an expedition max in 2019 I think. It was nice

Got a new maf sensor. Replaced the Delco with a Delphi. And the flex fuel sensing has not gotten better. Nearly at the end of another tank of e85, and it's reading below 60% and still dropping.

Now I'm thinking the exhaust leak is between the manifold and the cat. Somehow maybe I didn't get the gasket in the flange correctly before bolting it? It's not a bad leak, but it's definitely audible on cold start, and you can hardly hear anything once it's warm.

Always start with number 8.

meh, use a couple of right adapters and #8 is a piece of cake, I have a small 1/4" ratchet with a rotating head I just use a couple short adapters and angle the ratchet on there and slip a pipe over the end and it comes right out

Using a spark plug socket? The kind with the hex flats on the back end? Stick that on the plug and use a wrench or ratchet with regular/short socket on those flats. Nuttin to it.

Here’s my combo for #8. It works perfect, try it. It’s a regular depth 3/4” socket on the 5/8” plug socket. It’s the perfect length.
