What did you do to your NBS GMT800 Tahoe/Yukon Today?

[iamdub]

It actually wasn’t bad at all. I have been in auto collision for the past 15 years so I tried something with the vinyl that I usually do with factory decals.. have a bucket of fresh water and put 2 to 3 DROPS of DAWN dish soap… throw a brand new micro fiber rag in with it and buy a brand new plastic spreader… After cleaning the area you’re going to wrap very good with a whole different set of cleaning material you can then start to separate the wrap from the paper and just start soaking the roof with the clean water and also the wrap. This will let u be able to move it around a little and not just stick to the first place it touches.
Also I have done my homework and it is the exact same stuff that is triple in price. I bought the vinyl at hobby lobby it’s a whole lot cheaper and it’s the exact same product. Perfect for DIY projects.
Hope this helps.

I'm really considering doing gloss black on mine when I weld up the roof rack holes. Might even go full Euro and do the hood.

Thanks for passing along that tip about the Hobby Lobby vinyl. Is it wide enough to cover or do you have a seam(s)?

What they have in stock isn't I have to seems in the middle so three parts but you can order the wider one

I was actually considering the hood also but mixed emotions about it in my household

Installed some new LED door lights. I put Led bulbs in the stock ones when I bought it but two of the lenses broke so I bought new ones on Amazon. Highly recommend them

I just bought some but they’re all white, no red.

I think I might've figured out why it's running like crap once it's "warmed up". It's been going on for a few months now. When it's cold it runs fine, and once driving it's running really rough. You can even hear it in the exhaust. I noticed the temp gauge doesn't go past 160, even if it's been driven for awhile. I'm thinking the thermostat is staying open, not allowing it to go into closed loop--just a theory. I haven't been able to confirm the temp with the tech 2, but I'm pretty sure that's what's going on.
After driving for 20 mins--
Opinions?

I would agree that the thermostat is the most logical culprit here. Thankfully it's relatively easy (and cheap) to replace so I'd say go for it.

Or, less likely, the engine coolant temp sensor is mis-reporting to the PCM.

Even if the stat was stuck open, wouldn't the entire system reach normal operating temp at some point? Unless it was like 0 degrees (or below) outside, wouldn't it get there eventually after running for a while (even with a stat stuck open)?
While unlikely, as you say, I would still be willing to think the sensor sending suspect data to the ECM is still possible.

How bout this one?

I think to place them on the sides of the engine, the idea is that, I will post the photos when I run the experiment

Evap code is back. Recently did the vent & purge valves so today was playing detective to find the leak. Pulled the vent valve hose and stuck a cork in there to seal it up. Pulled the purge valve hose and blew air in. Can feel the leak. Hooked up a low pressure feed from air compressor to the purge valve hose and started listening for a hiss. The hiss and some clicks definitely coming from the top of the gas tank. SOB. Guess I have to drop the tank now. Just filled it up yesterday.

The heat comes out ok from the vents. What's a good way to tell which one is the issue? Thermostat or the temp sensor?

 

[Fless]

A scanner should have the PIDs to show the Intake Air Temp (IAT) and the ECT in live data; you could compare them cold, then as it warms up a bit to see if they track.

touch both heater core hoses. if they are hot hot like normal the sensor died, its a two part sensor, one 1/2 sends info to the pcm, the other to the cluster. if cold/luke warm the t stat is likely open.

Replaced output seal in transfer case, changed front/rear diff fluid (Lucas 75/90). Will change tranny fluid next week...

I wouldn't do it in flat black cuz it'll look like you were in a wreck and never painted the replacement hood.

You are going to be well above freezing today in NJ. Like 50+... I can't see how the system could be at 160-165 with a stat stuck closed or open.

If you still read that low, I would be shocked to hear it was a bad stat and not the sensor (or wiring/connectors). Maybe it is not always a high probability in a lot of reported issues, I think @Fless original hunch might be onto something. Keep us posted.

Machine shop called. Heads pressure tested good, cam bearing hole isn't wallered out, and magnaflux showed zero cracks. Now to decide if I should just slap these pistons in or go to flat top, or 5.7. I'm gonna ask for some prices when I pick the block up, that should push me towards re-using the stock ones, lol
That premium gas price has me re-thinking the higher compression ratio for sure.

I mounted the sensors, spartan work!!! ) (the kit has not yet arrived), I traveled about 100 km, at the moment no error code in diagnosis. Engine light off. The engine runs well on gasoline and also lpg
