Cold Start Idle Stays Hi Too Long

[Ehcees]

2006 Honda Civic Coupe LX 1.8 ltr AT (non Hybird)


ISSUE: When engine is stone cold & started at 80 degrees outside temp.
Problem: Hi idle of 1500 rpm takes 2 minutes to come down to 1000 rpm.

FACTS

1. Two minutes is much longer compared to all other cars owned & observed for hi idle time.
2. Dealer says no trouble codes & does not know how to fix. Miles are 14,000.
3. Owners Manuel does not provide specification for cold start hi idle.

4. Honda dealer has been asked same question posted on forum: HOW LONG SHOULD HI IDLE STAY @ 1500 RPM 80 DEGREES OUTSIDE TEMP PER HONDA SPECIFICATION?

4.1 Opinions as to how long hi idle should stay @ 1500 are not requested. Just the facts of factory spec are requested. Thanks.

5. Only vague answer from Honda dealer shop foreman is: Computer determines idle. Duh! We knew that.

6. Did call two other Honda dealers prior to bringing car in for service at third Honda dealer. None of the "Service Consultants" at all 3 Honda dealers could provide a specification for high idle rpm and/or time to stay at high idle at a given outside temp. Only one Honda Dealer could quote the curb idle after warm up. (975 rpm) But my Civic sometimes curb idles at 800 rpm & runs fine at this rpm.

8. Reason for concern: Trans does not like being put in drive @ 1500 RPM & sometimes make metal noise.

9. Agreed that 1500 cold start rpm & curb idle 1000 rpm seem OK, but that is not the question or problem. Ehcees seeks a technical spec answer as to how long cold start idle should stay @ 1500 rpm @ 80 degrees outside temp? Can you answer that based on technical documentation?

Ehcees 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. Larger font & text color shown is for easy read. This is a proper & allowed choice that will not change. Thanks for understanding. Please no comments on text composition, font size/color desired.

Why did you make a thread and a post about this problem?

See thread: cold start - high rpm in idle

[Ehcees]

To: Leon
Reasons include, but are not limited to:
1. Two minutes is much longer compared to all other cars owned & observed for hi idle time.
4. To find out: HOW LONG SHOULD HI IDLE STAY @ 1500 RPM 80 DEGREES OUTSIDE TEMP PER HONDA SPECIFICATION?
8. Reason for concern: Trans does not like being put in drive @ 1500 RPM & sometimes make metal noise.
Long hi idle wastes gas.

my si does that on a regular basis, and so do most others on this forum. I believe. i know ur car has an r18, but the programming can't be all that different.

My Si idles @ 2k rpm at start.

Same here and rpm's slowly drop to about 1500 in about 30-60 seconds. That's when I put it in gear and start rollin' out at 1500 rpm's. I think the r18 does the same thing but not sure. I never really paid much attention to it on my EX.

[Ehcees]

Please tell all of the following:

Cold start hi RPM?
Outside temperature?
Time from cold start to reach curb idle?
Honda factory specification for time to go from cold start hi idle to curb idle at a specific Temp?

Ehcess has a 2006 Civic LX Coupe, AT, 1.8 ltr. Hi cold start idle has been 1500 RPM @ 80 degrees outside temp. The Si appears to be 2000 RPM cold start hi idle, which appears different from the LX

[windforce]

Ok... So...............................

Windforce has a 2007 Civic Si Coupe, 6 spd MT, 2.0 ltr. Hi cold start idle has been 2000 RPM @ 75 degrees outside temp inside the garage. It takes a minute or two to drop the RPM to 1500, then I start driving. Btw, vTec kicks in yo @ 4500 RPM, and I shift at 7800 RPM every time I merge onto highways. Every time I take out the key, the RPM drops to 0.

kk?

Thank you for reporting data that is focused on the technical post question:
"my Si idles at about 1800 rpm at start up...! and rpm is drop to about 800 in 6~8 min...!"Ehcees values your input greatly. Can you tell the outside temperature that accompanies your data?

----------------
Data Summary to date is:
1.8 ltr > 2 minutes @ 80 degrees to drop from 1500 to 1000 RPM.
2.0 ltr > 8 minutes @ 0 degrees to drop from 2000 to 900 RPM.
2.0 ltr > 6-8 minutes @ temp unknown (probably 75) to drop from 1800 to 800 RPM.

Readers are requested to submit data.

your posting like an asshat...

why dont you use normal font that is not rediculously oversized and stop repeating yoursel? sayign the same thing 5 times ina row is not goign to get you your answers any faster...if anyhting it will tkae people longer to read this dumb thread.....
BTW this is a repost.

also...if you have been to the dealer about this, go outside on the lot and have them start up a new civic....look at how it idles and compare for yourself.

+elevently bazillion rep!!

Seriously, why the green, bold font? What is the point of copy and pasting the same information over and over? Like he said, this is a monster repost.

To: NIGHTHAWKSI & rmfa:
A. Original post requested Honda spec for hidle idle RPM & time.
B. If you can provide your hi Idle time, RPM & outside temp, then that would be a focused reply to a technical question on a technical forum.
----------
As to comparing with another Civic, that is the intent of B above request. Dealer will not allow Customer to speak/meet the technician. Ehcees cannot startup a bunch of new Civics.
-------------
Despite your complaints about repitition & request to Ehcees to explain font size etc., both of you Dudes have asked for reasons posted several times. Did you read? Please attempt to focus on the original questions concerning cold start high idle time & RPM. Think/Process/Focus.

well back to my original statement...reposting the same thing 5 times will not get you anywhere...once was enough in the original post and if some one wants to help you, they will. you cant force people to help by reposting the same thing over and over again...and it is VERY ANNOYING to read that font size/color you are using. no one is going to take it seriously.

as for the dealer not allowing you to meet any technicians or let you compare to another civic...sorry to tell you that they are just blowing you off. they damn well can....go try again.

why do refer to yourself in the 3rd person?
what did i ask for reasons of?
i cannot help someone i dont take seriously..your profile says your 96 , and located on earth...as opposed to where?

Your correct, the Honda dealer is just blowing Ehcees off & will not focus on finding out the Honda Spec for Cold Start Hi Idle RPM time. Suggestion to try again consists of:
A. Asking for Honda Idle spec here & other Owner's actual hi idle time on cold start as a substitute for inability to start up a bunch of new Civics on dealer lot.
B. Letter faxed to delaer service advisor that documents request for Honda cold start hi idle time & RPM.

B1. Dealer will not reply by E-mail. Phone message simply states what dealer shop foreman said in person after Ehcees broght Civic to dealer for evaluation: "Computer controls idle". The dealer is not technical. How can anyone know if computer and/or sensors etc. feeding data to computer are producing correct idle w/o comparison to Honda idle spec? This is warrenty work that dealer probably does not want to do.

B2. Next steps will include calling independent shops that only work on Honda & asking same spec questions. Since Ehcees would have to pay, these shops will probably admit the problem to get the work?

C. Third person reference explained several times prior along with font size & color. Agreed repitition is annoying. Please advise what Ehcees should do when repondents to my post keep asking same questions that have been answered several times?
D. As to my age shown as 96 & location Earth. This was done for:
D1. Comic relief.
D2. Ehcees is double the age of the typical Si Owner's that predominate this forum, hence why not totaly blow the young chaps mind?
D3. Location only matters in the real estate business. (more humor) Earth as opposed to Moon.

a. dealer is lying and can very well start another car.
b. hi idle time and rpm depends on many factors. will vary depending on ambient temperature, temperature of the engine when started, a/c on or off., etc...you will not get 2 exact same answers.
b1. the dealer is technical..tyhat is why they have dealer techs...shop manuals, etc...refer to a...
b2. next steps should be making appointments with other dealers. stop going to the same one if they are not helpful.
c. third person reference has not been explained. stop repeating yourself.
d.
d1.whatever floats your boat....
d2. there is a "geezer squad" you can join...search for it
d3. location matters very much wiht your scenario. as said before temp/humidity/altitude all change the idle and rpm.

lol...great information. too bad he cant compare because he has an r18....
