    The reason for preventive maintenance is to spend a little money in the present to prevent a much larger expense in the future. I don’t see how throttle body cleaning falls into that category. It’s something you do when it needs it.

    Sorry bubba, once again you're wide of the mark. Unless you post something from Toyota on how that particular breather system works, you got nuthin'.

    Had a Toyota tech say never clean the TB either, reason being over time as the butterfly wears the grime build up fills the void (to a point) if you clean the build up it will cause a high idle.

    Which it does, never cleaned the TB on my 435K mile 1st Gen, did…then it had a high idle. Toyota discontinued the TB for my application, so sent it to a guy in Florida to machine it and install a new butterfly.

    Unfortunately he is permanently closed now. http://maxbore.com/


    That said, on my new truck, doing all required services whether I think it needs it or not. So if there are any warranty issues down the road, it is all on record. Couple hundred bucks here and there, could save me thousands in the future.

    Can someone explain to me why carbon might collect on a throttle body? I’m skeptical that it could ever get that hot. I think people might be confusing this issue with carbon build up on intake valves due to direct injection. Valves are in the head and thus subject to a lot of heat. Throttle bodies not so much.

    Yes throttle bodies could get gummed up or corroded over time, but you can just wait until this becomes a problem and in the meantime focus on saving for that hood schwoop.

    Carbon is probably the wrong wordage to use (but accepted by most), correct word would be “Coking” it is just the build up of grime. Which happens even with the best maintenance schedule and filters.

    @wilcam47, maybe you don't understand those systems, or maybe you didn't read that very generic PDF you posted. Basically every manufacturer sets up their crank case ventilation systems differently; I would argue the one in the Tacoma is tuned to not feed crankcase gasses into the intake upstream of the throttle body. Prove me wrong.

    Coking is usually something like oil deposits that have burned into the surface from high temps.

    Have you seen yours after about 30k miles?

    I got quite a bit of gunk out.

    Mine is 2.5. Already getting corrosion from it, even me being diligent cleaning and putting protective spray on the terminals, it is still good, considering pulling it and swapping in an AGM like I have in my 1st Gen.

    Had the dealer do mine at the recommended 30K. They just did the brake and steering service too at 45K. Next oil change at 50K is the tans service and new front brake pads. Not getting the life out them like on my ‘99, auto in the ‘21 so on the brakes more apparently and not doing as much engine braking like I do with the manual 1G.
