Wallet cleaning

 

The only time I've needed throttle body cleaning is when the idle speed starts to rise and hunt. Then I just force it open with my hand when off and spray the pivot points.

Some cars the intake manifold really will sludge up over time. A catch can can help when put inline with the PCV hose. But then that's another maintainer item to take care of.

 

I'm told our 2023 Tucson will need a Throttle body service next 20,000 miles and it will be $120

 

Keep that money in your wallet

 

On my Genesis Coupe with ETB, the first one I've had, about every 5 years I have to spray some carb cleaner in the open throttle body at the pivot points. Also try to get the back of the throttle plate the best I can. I usually wait until it starts to idle fast and not normally. If I don't clean it it will leave me stranded in limp mode or in a mode I have to keep clearing to get home. Limp mode is cleared by a restart.....usually.

 

Don't waste your hard earned money on that so called "maintenance". Wait until you have some issues like engine light on etc. not cleaning the throttle body will not damage other parts of your engine

 

Since it's an easy DIY job I clean the throttle body every 50,000 miles on the fuel injected cars I've owned.
If I were paying somebody else to do it, I'd wait until 100K miles or some issue with idling etc.

 

I took my 2022 Tucson LTD with 17,000
Miles on it to Big Star Hyundai in Webster Texas. Without even looking at my car they said I needed 434$ worth of non covered maintenance work including throttle body cleaning. I left. I felt like they were trying to scam me. They also said 199$ if they determine my check engine light is bc of a non covered item.
