The engine idlees high to get warmed up, just give it time to warm up and lower the idle before you put it in drive. Try turning it on when its 0 degrees outside, it will take about 8 minutes at high idle

Ehcees seeks a technical spec answer as to how long cold start idle should stay @ 1500 rpm @ 80 degrees outside temp? Can you answer based on technical documentation?

If you know whereEhcees can download free PDF copy of 06 Civic Service Manual for LX & EX models, then please advise. Note that the separate Simodel is covered bydifferent Supplement Service Manual & does not cover or apply to Civic LX & EX versions for 2006.[/align]

Can you define "mine" by year, make, model & series?
Please tell the cold start idle RPM for your car based on your experience?
Please tell how long to drop from cold start idle to curb idle at a temperture outside?
Thanks for being specific.

 

Marty wants you to stop talking about yourself in 3rd person POV. It is retarded and reminds me of Sherman from American Pie

Ehcees always uses proper nouns & not pronouns. Reason is to avoid confusion as to who or what is being spoken about or speaking, as advised by experts for all web communication. This is a proper & allowed choice that will not change. Sorry if Marty isdispleased. No further comment on this topic is desired. Thanks for respecting my choice.

 

Well I was going to explain why your car does what it does , it is to warm up your Oxygen sensors so that your car will obtain it's best fuel milage as soon as it can.
