I am the second owner of my 2016 6.2 Yukon. After a few weeks of 8 speed shutter driving and a blown fuel injector seal on cylinder 8 already. I decided to look into a VSC and with the advice of my GM service rep and went with Endurance. the vehicle has 87k miles and they will give me 5 year 100,000 elite coverage for 4000.00

I am getting a P219B. I just finished with the CRC and still no good. Under the hood it sounds like a air leak. No other codes but idle is rough. I did see a good amount of smoke after the 30 minute wait period so I know I didnt waste 30 bucks on nothing. I guess its off to the mechanic cause it seems to be getting louder.

Of course I will take it more seriously than this fellow. Yes I am really going to do it. And I want to paint the "GMC" in red. Maybe some model paint for that?

I didnt want to turn this into a top cleaning thread. Im the only one who gets nervous using products with hose adapters and such that with my luck will get sucked into the engine? I love the vinyl tube method for this reason. If I can find the chemicals you stated in a liquid form I would feel much better about switching from seafoam. Thanks again for your advice..

Thanks 14Burrito !

I'm a Rum drinker I did google first all I could come up with was the tap method. Maybe I should look harder?

I have never used plasti dip But after using flex seal on my rain gutter and am very temped to spray the black version on my 22" stock rims.

Does anyone know of a video of this "pill swap" The only thing I have ever "tapped" was a woman.

Yes I agree. I bought it used last month. The service records showed top cleaning at 60 something thousand. I tried the spray can seafoam but the hose kept getting crushed and not much went in. I just put on a CAI and I will use a vinyl tube and a funnel and pour liquid seafoam into the throttle body . I did wipe the butterfly when putting the CAI on and it was clean. So I think plugs need to be done asap.

Has anyone tried the NGK 90220 {#LTR5AHX} Ruthenium HX ? Im at 86,000 and have some minor shaking during idle so I am gonna do my plugs and wires. I am considering paying the extra cash for these. I remember how well my old truck did when I installed the iridium plugs. Hoping these will benefit my 6.2L with the Ruthenium. Also anyone go with aftermarket wires?

I only drive in Tow/HaulAss mode. So this is not in use then correct?

Are you using the Mobile 1 ATF fluid as per the TSB?

As the previous poster mentioned, you can have a brand spankin new ride feeling with shocksims and the struts and shocks of your choice. It will be also be 2000.00 less than replacing with GM parts at the dealer. And the front struts are rated "easy" for the home mechanic to do, that will save you even more $$$

Mine shuttered at 86000 at low speeds. Paid a dealer to do a flush and filter change with the mobile 1 ATF . They nailed me 600.00 cause it was out of warranty but the shuttering is gone for now. I hope mine is the 200k miles one

I have the dreaded 8 speed, it does jerk from first into second but after that its good. I am currently reading up a getting a trans tune to lower temps.
