Idling problem, hv done searches but no result found

hi mates, my CRX with B16A2 idles a bit high (around 1500rpm) when cold.
the problem is it doesn't go down even hv been driven normally for 15mins,
anyway the temperature pin just won't raise.
i m pretty sure there's nothing wrong with the TPC,
becoz when it's warmed up it idles at 600-700rpm which is pretty normal i reckon.
the thing is it's taking far too long to get warmed up.
i hv done some researches and most likely there are issues with IACV or FITV,
just i don't know where are they located and how to get it done :S
apart from IACV and FITV, what might cause the problem?
any answers will be appreciated :)

problem fixed, it's thermostat releated
close post :D

if ur temperature pin wont raise the sensor could be faulty or maybe your thermostat is stuck open

sorry mate abt the misleading
the pin would raise actually
but it's like after 30mins of driving
thz for yr answer btw :D

Thermostats slightly opened mate.

Had it on my DC2. Pretty common on B series. Itll only get worse. Highway driving youll always be in the cold position.

^^ Repped!

and rep to 2mprs too. (damn,gotta spread the love 1st :) )

mate that's exactly the same thing happened just this morning
how did u fix that? *O*

change the thermostat they are cheap search the forums or google pretty easy to do.

just read some articles abt changing the thermostat of B16 in google
it looks a bit too complicated to me
if handing it to mechanics
how much would that be
cheers

no clue mate i do my own. its acutally pretty easy all u gotta do is drain the coolant remove like 3-4 bolts and the thermostat just pops out.

my uncle is going to rip my head off if he finds some coolant or oil on his floor lol
but yeah, will see if i can do that myself :P

thermos are easy to get out just not easy to get to in some models, b16 from memory shouldnt be to hard. Also make sure u have the gasket, if the thermo housing been tight for a while the gasket will deff rip. and check your coolant temp sensor.. you prob wont have to drain all your coolant just top up some... and make sure to bleed the system before your first drive with the heater tap on HOT not cold.....

I dnt know if i have the same problem but what my crx does is that it bounces off revs at idles 1500rpm then goes up to 1800 then back to 1500....

wat seems to be wrong any one know
it warms up ok I THINK

clean your iacv, fitv (Beeza has posted the diy's for this) or it could be a vacuum leak

mates i just found another problem
my car is jerking when changing from 1st to 2nd
actually it happens along every gear
just becoming less noticeable as the gear goes up
my uncle (who's a very experienced driver) points out that there might be issues with the clutch
in stead of just the IACV / FITV / thermostat problem
just in case, the worst case :S
how much is the parts + labour for doing the clutch up
wt if i pick an exedy heavy duty clutch
does it extend the clutch life?

again, thank you all guys for yr generous ideas

parts for excedy heavy duty clutch..$400+ approx and for labour depends.. around 300-500 - depend where u go..
imo fix the iacv & fitv (for cold start idle) then go from there.. check for vac leak..
hope that helps buddy :)

i had both problems with my dc2 integra, firstly i replaced the thermostat which i think is about $40 from honda and took me like half an hour to change
and 2ndly, the jerking could be a broken rear engine mount, clutch is relatively expensive so check it out properly first

mate this is the first time i hv heard abt the issue with rear engine mount,
could u tell me how could i check if the problem is from the mount?
thz heaps!!

1. physically look at the mount
2. grab the intake manifold and see whether you can rock the engine back and forth(with it off and cool of course)
3. lifting off the throttle usually results in the shifting rocking back and forth too
4. pop the bonnet and watch the motor and rev it at the same time, excessive movement could mean a broken rear mount or torque mounts
