A few weeks ago I added BG Platinum 44k fuel additive, anticipating the work today. Within a tank, responsiveness was better.
Today I removed, cleaned, and reinstalled the throttle body. Clearly prior service I paid for didn’t remove and clean it like they said they would. The pattern of deposits on the back side looked older, thicker, and was harder to remove than the film around the rest of the throat, which came off easily. A little extra time, cleaner, and a bit of elbow grease got it all.
I am a first timer doing this, and it’s like


at best. Maybe 40 minutes at most. (I also cleaned my 2021 GX 460 throttle body while I was in the mood. Much lower mileage, even easier to clean up.)
Don’t put this off - It’s one of the best bang-for-your-buck DIY maintenance items to save money. This is a way over priced item if you pay for it. Plenty of guides out there to help. I think I saved about $600 today between both - compared to dealer pricing.
