    2018 GMC Yukon Denali question on how to clean my fuel injectors and carburetor

    I just use the Berryman B12 Chemtool - it's its own bottle on the shelf - the whole kit isn't really all that necessary. CRC MAF Cleaner would probably be good, too, but, just cleaning up the intake tract and TB - I see no reason why Brakekleen wouldn't be the go-to.

    G80 replacement

    Uh, I'm a Centennial -- do what, now?

    G80 replacement

    I'm gonna be an аhоlе and bump this - How'd it work out, OP? What did you eventually end up doing? I'm looking at Eaton rear diff and getting mixed answers - Grok says the forums swear by the Eaton LSDs, so, I'm sold, there, but, getting mixed signals on part numbers. Grok says 914A538 and...

    Installed Brembo big brakes on all 4 corners of my '19 Escalade!

    I like those wheels - looking at getting a set that I'm eyeballing on Marketplace, locally. So, the brakes fit under the rears, but not the fronts? At 3/4" spacer, plus longer wheel studs and the rest, are you anticipating Mеxipoke, or just a slightly more aggressive stance?

    AOS mileage drop?

    I should probably expand on my theory.. Sorry. Remember we had vacuum-leak-like symptoms when the AOS was installed? My theory is thus : The new valve breather hoses supplied with the KN intake weren't sealed like the factory ones - not loose, but, not airtight. The addition of the AOS...

    AOS mileage drop?

    So, I haven't reinstalled the new AOS, one thing at a time, here, but, I did want to address something that's not entirely visible from the pics - vacuum leak. The intake came with new hoses and connections for the valve breathers, but, they're not sealed, at least, not well. The hoses come...

    Vibration Idle

    All good things to check, but, in my experience, that idle shake goes away after a solid cruise - how often and for how long are you driving it? I just returned from a road trip and at destination, in-town idling at lights, and while parked, the shakes I had previously experienced were...

    AOS mileage drop?

    Thanks! Getting married for the first time at 40 is.. Interesting. I would love for us to be even ten years younger, but, I had some real growing to do in that time period to be ready for this. Our own personal history is important, which is why I have few regrets. She absolutely lets me do...

    AOS mileage drop?

    Much of this is probably, "new parent syndrome," but, I'm used seeing the oil pressure no lower than 30, so, when the temp is hotter, water temp is in the middle at 210, and I see the oil pressure drop down further than I've seen in the 3mos I've had it, I'm gonna start asking some questions...

    AOS mileage drop?

    Got the oil changed and no change to oil pressure at hot idle - still hovering around 20psi, according to the gauge. Dealership did the change and a, "multipoint inspection," and came back with nothing wrong. They're the ones warrantying it when there's a catastrophic failure, so, if there was...

    AOS mileage drop?

    I think I have a proximate cause : Fuel dilution. Last long highway cruise was about a week after I got the truck, in July. Since then, it's had probably 1000mi at least, of short trips. After an ECU reset, the shifting and driveability issues went away (so far, fingers crossed) but I'm...

    AOS mileage drop?

    So, this turned into a doozy.. Symptoms disappeared when I reverted back to the stock hose. Today, while running errands, all symptoms returned, rather mysteriously. Additionally, oil pressure is now closing in on 20psi at idle at stoplights.. Didn't used to do that, and did appear during the...

    AOS mileage drop?

    I've emailed JL, they responded with a video to inspect the o-rings in the hoses, as sometimes they can come unseated. Mine were fine, upon inspection. They're sending a replacement and I'll send mine back for inspection.

    AOS mileage drop?

    It's not just mileage - throttle response and shift points, too. Put the stock pipe back on and all of those things improved. I really wanted to like this thing, too. After about 25-30mi I had a ~1-2ml in the can, so, it definitely works! But that juice is just not worth this squeeze.

    AOS mileage drop?

    That's kinda what I'm thinking, but, I don't understand how that piece itself could be a vacuum leak, since it's the only part that was added. I think what I'll do is disconnect the neg terminal and do a soft reset, see if that changes anything, and then barring that, I'll switch back to the...
