    Yukon made it 1400 miles before breaking down again, it's cursed.

    I'm just ranting.. feel free to disregard.. I have a 15 Yukon, I recently; two months ago, I rebuilt the engine myself and had the trans done by a shop. Everything is great, I didn't have to go back into the engine at all once I was finished. I was pleased.. No errors; no lights, I handed it...

    Replacing magnetic ride struts question

    I'd replace it wit OEM stuff. It'll ride like new. The front shocks are super easy and the rear are equally as simple. It's like a 2hr job, max.. Maybe 4 if you're quaffing beers and kicking tires with your buddies.

    6.0 Engine and Transmission Emergenct

    Without any logging, we're just guessing. You sure you didn't accidently hop into someone's Ford truck? ;-) They tend to act out like this.

    Which tuner to disable AFM?

    I started with my Ford 6.0 diesel, which is a simpler operating system in comparison to this Gen V stuff. I'll send you a PM and see if our schedules sync up. This is the best Gen V training, bar none--> evansperformanceacademy.vhx.tv

    Which tuner to disable AFM?

    I have a solid grasp of this and if you want I can walk you through all of this offline in a teams meeting. There's a little more to it than just turning off DOD in the ECU. I can also share my logging channels and histograms. This is the "Wife approved" trans shift template that I put...

    Should this pre-purchase inspection be a dealbreaker?

    I mean, if your wife doesn't approve that's one thing; and I get it, now might be the time to return it before it's too late. But returning it because of a mismatched shock? I'd just say you don't like it. Did you do more than 1500 miles??? Across the country is more like 2400 miles.. And you...

    Would you buy this?

    I can vouch for the problematic 2015's.. I've replaced/rebuilt the -air con, engine, trans, GPS antenna, tail lights and shocks. And now a $700 head light is going bad.

    Should this pre-purchase inspection be a dealbreaker?

    You got the 125 point FREE inspection.. If you want the 150 point inspection; for the low low price of $29.99, they open their normally closed eyes and check the shocks and tire pressure. lol Seriously though. None of what you describe would be a show stopper to me. Those pumps make noise.

    3 kids, 2 headphones=problem

    I don' t know to be honest. I have the 2015 Denali and it's head sets don't work. I've looked in the factory tool and didn't see any configuration for the headsets but it's not been a priority to chase it further.

    Lets play a game of what caused it....

    Ok.. This hasn't been answered yet so I'm giving it a shot. hard to start? Fouled plugs and or mechanically gapped plugs Chugging white smoke?? Coolant leak in the combustion chamber... Reduced engine power? This is due to the other obvious signs, by design No idle? Large vacuum leak.. or...

    Occasional light lifter tick starting

    Hmm... This is a 'zen and the art of motorcycle maint' moment.. Do you let it go and replace the engine/parts when it tears up or do you fix it now? If it wasn't such a clean truck, I'd let that sucker tick and smoke until it gave up it's ghost.

    2005 Tahoe Z71 Stability System Disabled

    I fixed my stability errors with the GM diagnostics tool and updated the body controller firmware while I was in there. I was able to solve 90% of my problems with it so I guess was worth the price of admission.

    Just had starter replaced, won't start.... What can go wrong???? FIXED

    Hey, check to see where the battery ground is located. It should be on the engine. And if there's a 2nd ground from the main bat cable, it should go to the chassis. I'd check the grounds on the back of the cyl heads as well.. and any others you come across.

    '23 down; massive oil leak | suv's don't get lz0's?

    Sales people aren't always the most truthful and the service dept didn't sell you the vehicle.. Often times, one needs to re-align their expectations with reality. And I'm speaking for myself as well.

    Lifter failure

    I'll rephrase what I said... My warranty ran out and I bought the GM factory diagnostic tool so I don't have to go back to a shop or dealer. I posted a link to the actual tool and the site to find the tech-line subscriptions.

    '23 down; massive oil leak | suv's don't get lz0's?

    I think there's an emotional aspect to the purchase of an American vehicle. Like Harley Davidson, no one buys an FLH because they're the best at what they do.

    Best sounding muffler for 5.3?

    I have the flow master 70 series 'big block' muffler on my 15 Yukon.. I like it.. It's a mellow rumble. And... I can hear my wife coming from up the street.
