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

[Nyjetfan21]

I went to a dealer for my routine oil change and they gave me a bunch of different things what that were wrong with my 2018 GMC Yukon Denali. My oil coolant line is leaking. Front and rear shocks and struts need to be replaced due to leakage. Fuel injectors and carburetor needs to be cleaned. The question I have is can I clean the fuel injectors and carburetor myself at home instead of paying for their service? What is the best method and products to use? If there’s a how to video that would be greatly appreciated. Here is a picture of what they said about that situation.

We stopped using carburetors in the late 90s…. It’s all electronic fuel injection…..

I meant to say that throttlebody I’m sorry

I meant to say the fuel inject is in the throttlebody not the carburetor. Sorry for the misinterpretation.

you could use the berrymans kit and buy the throttle body cleaner and maf cleaner and a new air filter and some rags and be all in for less than half of what they are charging for the essentially the same service.
doing it is pretty basic,,, probably a 10,000 how to's on you tube.

Ahh that makes more sense. Yeah all the parts stores make product for that that are cheap to get a hold of and a thousand how to videos on YouTube.

By any chance is this the kit that you are talking about? Do I still have to take a pot the throttlebody and clean it and wipe it with rags and throttlebody cleaner as well

I too am thinking about cleaning my injectors on my 2018 Denali. Curious how you make out.

I used this exact additive. Wow. I felt difference on a 14K, bought new Jeep V-6. Try it!

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.

I’m having trouble finding the Berryman kit. Is there any reputable place where I could order?
