I get my car serviced at a Lexus dealer every 5000 miles. My 2006 currently has only 35,000 miles.
At 25,000 miles dealer said I needed throttle body cleaning. So I had them do it. Now, at 35,000 miles they tell me I need another throttle body cleaning. Could this car possibly need a throttle body cleaning
again? I declined the cleaning this time.

Is using a gasoline additive or cleaner going to accomplish the same thing? My dealer has a very high rating and I do trust them. They've always been great.

Your opinions are welcome.

I don't think there's any way that you would need another cleaning in only 10,000 miles. Even the first cleaning at 25,000 miles seems too soon to me. I cleaned my 01 with 170K for the first time a few months ago. To my knowledge, it had never been done before.

 

You have reason to not trust them. There is no reason to have TB cleaned so often. They are just trolling for service dollars. What did they charge you for the TB service??

 

You can actually do the cleaning yourself. It was wise of you to say no to them. They are just making an extra penny out of ya.

 

No, I declined the service. So, let me know how I would DIY.

Cheers

Not your year but gives you the basic information.

 

I clean my own every 30K mi. I use a stainless toothbrush, cotton rag, and carb cleaner. Do not spray the carb cleaner directly into the TB since there is a sensor in there (IIRC, at 12 o'clock). The old Toyotas don't have the sensors (whereby you can spray carb cleaner directly into the TB). You should only have a little carbon buildup around the flap after 30K mi. When you work with the TB, make sure the key is NOT in the ignition or messing w/ the flap might throw codes.
