I'd be more interested in what caused the buildup at your thottle body. Is it coming in with the fresh air or one of the hoses connected near the thottle body. If I remember right, both the PCV hose and the evap/purge hose is near the same location. I recommend doing some investigating, before getting it cleaned.
Fuel induction cleaning
Hey everyone, I’m getting closer to the 100k mark. I’ve been religiously avoiding fuel induction cleaning/ engine flush services since after reading that Ford themselves told everyone and sent letters to dealers that they do not approve any fuel induction cleaning service. However, as I reached 90k miles now a tech noticed there’s a lot of build up and some corrosion in my throttle body. So, they recommended a fuel induction service, especially since it’s been longer than 2years(the recommended time to do the service). I’ve heard stories that this can cause deposits to basically ruin the turbo du to being incorporated in the manifold. I’ve also seen that some people have done it with no issues. My car has been feeling sluggish and not as smooth as it once was, regardless of all the power it’s making rn. I just got the NX2 and I don’t wanna ruin it already. What does everyone think is the best option?
don’t do it, save your turbos!!!
or
well, it’s about d*** time you cleaned the engine!
Thanks everyone!

It’s most likely due to blow by. And also carbon build up is normal on almost all vehicles, but especially direct injection. Since it’s at 90k miles, it’s probably just accumulated over time. But I do think it could be from blow by, I never ran a catch can do it could have been a good considering factor to what contributed. Ofcourse, without a way to really see/test it, this is all just theories. But that is probably what caused it from what I can gather causes carbon build up on intake manifolds and throttle body’sI'd be more interested in what caused the buildup at your thottle body.

I have close to 90,000 miles on my Ecoboost Fusion, and I've never checked it for carbon build. I probably should pull my intake manifold and do a little house cleaning.
However, on my Ecoboost Mustang, I've had the intake manifold off a minimum of 3 times. Once to clean, motor oil out of it when my factory PCV failed. Most of the bolts are acceptable from the top, but there are a few underneath, that you can get to from above, but it's a lot easier if you just crawl under the car.

Never done a fuel induction clean on any car I've owned. My mustang has over 150k on it now DD FBO and custom tuned
The best solution to cleaning intake deposits on direct injected engines is walnut shell blasting. Fortunately, the Mustang Ecoboost engine has an intake manifold that is simple to remove. Once removed, access to the intake valves is easy. I've seen videos on this process and it's very effective. Additionally, while the manifold if off, removing and cleaning the throttle body is a snap. Make sure to use the spray cleaner specifically designed for throttle body cleaning, as it will not damage any coating that may be on the throttle body.
