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

[Tonyrodz]

I uh, gave her the onions from a stop.. first time I really got her going since the work has been done.. couldn’t help myself, as daughter and I were blasting some Master of Puppets.. annnnd I did not expect that..!! View attachment 376722
G80 putting in work.. I better upgrade this rear end before I blow it up..! @Tonyrodz

@Sam Harris , yup that'll do it, but it's so much fun lol.

Checked the header bolts real quick and looked it over under the hood for any loose connections, or anything sucking air--nothing visible, everything feels tight. Fuel trims are still off between banks 1 and 2.

Have you ever searched LKQ for a 2nd row seat? They'd be in much better shape then front seats. Probably lots floating around that's never even been sat in.

I have looked, believe me. There’s nothing around here in any yards at all, and online I can’t find any that aren’t worse than mine. These are 21-23 years old, second row- not third row. My third rows are in great shape, stored away. The 00-02 Denali’s are the only ones in my color combination (two tone). Not the 03-06, not the Tahoe or Burb.

I remember--that dark pewter in the center and shale on the outer. I'm really curious on that leather product you bought to repair the scratches.

I’d be on it if not for the patio roof project.

I'm sure. Your hands are def full at the moment.

I hate how things like work, chores and obligations get in the way of getting to things like fun, hobbies and vacations! They're running back to school ads already and I haven't so much as looked at a beach yet this year!!!

My ac in The Beast isn’t super cold this summer. I’m thinking it’s low on refrigerant, actually pretty sure. 2 years ago it was super cold, last year seemed a little less cold, and this year not very cold at all. Opinions on whether I should try adding a can or should I just pony up and pay to have it recharged? Who has used the cans from the auto parts stores, and is there any preferred brand?

134a is 134a.

Best to have somebody put gauges on there if you have an HACR or HVAC buddy.

If you just go for it, do a little at a time. If you overcharge it, your compressor will ultimately end up paying the price.

Mine had this same progression. I added a couple cans using the cheap gauge that comes with the can. I also monitored the vent temp in relation to the ambient temp cuz I don't trust those gauges. It's chilly now. I kinda don't care if it blows up cuz I wanna replace the major wear components, anyway. I just want it to last until winter. I'm sure you already know to NOT use the stuff with the leak sealant. I used the cheapest 134A Walmart had.

Have been ignoring P0496. Got a new purge valve solenoid for $36 with 20% off bucket sale at NAPA.

Mine had a plastic elbow fitting on it, which I did not see in YouTube videos. Simply squeeze the gray clip-tab-thing and the elbow slid easily off the purge valve.
What I expected to be 10-15 minute job potentially fighting a stubborn hose directly connected to the part, turned out to be about a 5 minute job to swap out the part with the quick disconnect fitting!

New part does not come with the gray silicone gasket that goes between the intake and the purge valve. Make sure you hang on to the one that is on there...

I just remembered my buddy that owns a body shop can do it. I’m dropping it off in a few days, need to leave it with him because he’s super busy.

Two weeks ago, mine was leaking from the high side port. Had it vacuumed, new port, fill. It sat for two weeks. Yesterday, barely blowing 70*. Looked under the hood, heard noises - low side cap was covered in oily green grime. Going to take it back. It pains me to pay them for $10 parts that screw in, but in my older age, I'm a little more considerate of the environment as I don't have the recovery tool.

The Schrader valve is leaking? Man, that sucks - I thought it was only the high side ball valve that had a habit of leaking as it gets older. Hey, at least you're too knowledgeable to fall for the shop quoting you on a full rebuild you don't need!

A dumb question is the one that is not asked, so here we go...
If the Schrader valves are having slow leaks and not ******* (auto-censor LOL can't say p.i.s.s.i.n.g.) out full force... Can Teflon tape be used on the cap to seal the leak?
May not be THE solution for yours, but I would think it might work in some cases where leaks are slow.

The cap is just to keep dirt out, not meant to be a seal. The schrader is basically a tire valve with a plunger and o-ring. My high side was leaking years ago and I put a new one in because everything had already leaked out. Then I took it in to have it charged.

replaced my fuel pressure regulator a few weeks back... everything was good but now I am noticing acceleration is a little sluggish and cruising at 70mph i can feel a little roughness like it may be the fuel/air ratio. cleaned MAF and intake filter. still a little wonky, so much so it messes up my shifts a little.
gonna try and put the old one back in and see how it runs

Why did you replace it? And was the new one OEM?

It wouldn't hurt to verify the proper fuel pressure after changing the FPR, or when you have trouble like this. Lots of auto parts stores will rent a fuel pressure tester for free under the loaner program.

Technically last week, but I replaced the fuel lines on my Tahoe, and today I sealed the rear diff cover. I’ve noticed a few spots of gear oil in the driveway lately, found a relatively new cover with a few loose bolts…

 

[ncalvo]

When starting my truck it took a couple cranks before turning over, it wasn't bad but noticeable.. for a while i just simply clicked the key to power let the fuel pump prime for a moment before starting.
I replaced it with an acdelco.
Ill try and check proper fuel pressure thanks for the tip. Also gonna try and put the old one back in see if there's a difference.
