I have a brand-new MY07 S2K, and in my opinion the idle speed on a cold start is too high. This is my first S2K, so I don't know if they all do it (which is why I am asking you knowledgeable gurus here )

My beast idles at 2100RPM from a cold start which I feel is excessive - a more comfortable speed would be in the region of 1100 - 1300RPM. My other Hondas (MY07 Accord Euro and MY06 FR-V) don't do this, and indeed idle at a sane RPM when ice-cold.

Maybe it's only the performance Hondas that do this - I used to own a 2.2VTiR Prelude that used to bug me in the same way. I belong to the old school that holds that you REALLY nurse that engine when it is cold (I don't exceed 2000RPM until I have a reasonable (water) temperature reading, and then I don't exceed 3500RPM until 5 minutes after that point - when the oil temp has had a chance to stabilise). Then, and only then, do I thrash it if I have to.

If I approach my dealer with this question, I KNOW I am going to get fobbed off - and nothing will happen. What I would like to know is if this fast-idle / choke setting can be programmed / altered somewhere in engine management? I'd like to take it into the dealer, and say 'Do X, Y and Z' and know that I am speaking from a position of knowledge.

Thanks in advance!

Cold idle at 2100RPM is normal. Give it like 3 or 5 mins it'll drop to 900RPM.

 

They idle high to begin with IMO.

mine is exactly the same, its perfectly normal. Honda wouldnt have made it do it if it werent right...no worries!

 

if u shift before 1900 RPM, ur actually bogging the engine. This is not the way to drive the S. No matter if it is a cold start, shift at 3500-4000 will be good enough. When ever the car got started, that means the oil has lubricate all the internals already. Then why u should still concern about the RPM? just dont hit VTEC is ok. Theres no point to shift that low and bog the engine.

 

I agree, i just tried the whole shift low for gas mileage...ran upon the MPG thread someone said to try shifting at 3500-4000, so now i shift at 4k, i go places faster, and i get BETTER mileage! roughly 23 with both highway/city/vtec. Good enough for me

I do however tend to shift a bit lower for the intitial 4 minutes or so for eveything to warm up nicely before getting on it or anything.
