I was at the deal/stealership today for routine servicing and they asked me if I wanted to clean the throttle body. Mine is a low mileage vehicle and I'm cheap, so I said no.
Any hybrid owners here done a DIY throttle body cleaning? I was thinking of buying a can of cleaner, disconnecting the intake hose, spraying the inside and wiping off any gunk.
Do I need to disconnect the 12V battery in the back? Any precautions on sensors or moving assemblies in the throttle body?

You don't need any type of throttle cleaner if you are using a Top Tier gasoline.

Isn't the throttle body upstream of the injectors? Maybe the hybrid's Atkinson cycle running lets the air-fuel mix leak past the intake valves and get stuck on the throttle body.
Yeah, I guess it was more of a wallet cleaning procedure than a necessary service. A 10-year-old car might need it - see the LS and older IS forums on this - but it's not recommended for newer cars.

Geez, another scheme/item recommended by the dealer that's not necessary. I didn't know this but do now... Great forum...
