Cold Start Idle Stays Hi Too Long
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. Too Long.
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? ----------
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. Dealer has no specification for time or RPM>High Idle.
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 uses proper nouns & not pronouns. Reason is to avoid confusion as to who or what is being spoken about or speaking. 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. Ehcees is sight impaired.
