Update - Honda dealer cleaned the throttle body - this reduced hot idle from 1100 to 800 RPM, but the dealer said they checked with Honda who said there is no spec on max cold idle speed, which remains at 1600RPM.

How could your throttle body be this dirty on a 2 year old car?
If this helps, my car idles at nearly 2k RPM when cold, gradually dropping to 1.5k within a minute or so.
When warmed up idles at 700. 900ish with AC on.
That was what I asked, the dealer said it was quite dirty & I should clean it each few years.
Thank you for that. My concern is at 1500 RPM when you engage drive, & hurting the transmission?
Seems a good outcome;good to see!
BTW Did the work bring improved fuel economy? My car was 11 months old before first sale, and is a little heavy on petrol, around town, at about 13l/100. Out of town things change. A recent 600k trip, mainly on freeways, returned 7.3l/100k. The car has done 12,000k's.
BTW2 anybody know why Honda puts the fuel figure-sticker, in front of the driver, whereas other makers usually bung it on the other side.
CHEERS

Fuel economy improvement is hard to tell. I assume the reduction in hot idle should be positive to fuel consumption. On freeway driving I can get 7 to 8L / 100K but I also get this from my ten year old VZ Commodore (After I serviced it).
Around Sydney in usual commuter stop start traffic I expect most cars in the 2 to 4LT range will get 12 to 16/100K, it depends mostly on the traffic & having to re accelerate often.
Don't know about the sticker.
