Idle issue

[jrstyles]

Hey guys just letting you know that i've read the threads already.:thumbsup:
i own a dc2 and its having idling issues (high rev, back to low etc). Ive cleaned my throttle body and that didnt help, also cleaned up the iacv following this guide http://www.team-integra.net/sections/articles/showArticle.asp?ArticleID=1174 and its still being a tard :(.. Any ideas what else it could be? My mechanic quoted me $200 for some part im not even sure of but seeing as he is a friend of the family, yeah. Any ideas what the problem may be?
Thanks, jason

need more description on the idling. Happen all the time?. When cold? any different with clutch engaged/disengaged. But if you have already cleaned out those two then, try looking for a vaccum leak any were, maybe look for some holes in the intake mani that are exposed. Or Check the Throttle body and see if the flap is closing properly when closed.

sorry for the brief description.
-It happens all the time
-From cold start my rpm almost hits 3.5k and keeps revving from 1.5-3k but when it warms up it 1.2-2.5k
-Clutch engage would that be foot on or off the pedal? (foot on the pedal it idles like this)
-I've taken my intake hose off and have checked the butterfly valve whilst pushing on the gas and there doesnt seem to be anything blocking or preventing them to open/close properly.
Another thing i've noticed since this has happened is that the exhaust smells, not exhaust smell.

you might have a vaccuum leak around the TB area.

hi i have a similar problem . my idle goes from 2k to 0 from cold start after awhile it stops . this has never happen before . how can i fix this? dont know where else to post so i add on here.

I had the same problem with my DA. Turned out to be a broken hose from the back of the TB.
The Mechanic found it by mistake it had a little whole. so fitted a new hose and it was fine.
check for any leaks.

Just say what ya mean man.

mine does the same thing every morning ever since I got it. since mine doesn't have a tachometer (Breeze) I can't tell how many RPM it is doing but I can tell from the sound, after 1-1.5min it'll go down halfway then go down to the usual rev. but the idling is smooth not hunting or fluctuating.

happens to me every morning, when i start dc2 up it idles from 0-2k range until it warms up.

could be a vacuum leak

have the same problem certainly throttle body related. try some cleaner told that helps

[kraftycuts]

This could be a result of different things..

Did you check/replace the TB gasket when you did the clean?
Did you also give the IAC (Idle Air Control) a good clean? This one is important when cleaning the TB
Is your PCV (Positive Crankcase Ventilation) valve clogged?
Is the throttle cable properly lubricated and not sticky? is the tension set correctly?
And as others have been saying, it may be a vacuum leak. You can check for a leak if you cover the throttle body opening with your hand while the engine is running and see if the engine cuts off. Try to be careful though, the vacuum pressure is quite strong.
