EACV control the revs?

[altong0840]

hi everyone~ i just want to know is the EACV control the revs higher (1500rpm) when the engine is dead cold? and keep the idle to 900RPM when the engine warm?

because normally my D15B4 is rev up to 1500rpm when it dead cold, and it idle at 900rpm when it warm. but recently it is 300-500rpm when it dead cold and 900rpm when it warm.

it also losing revs when i turn on headlights, even the deforst the rear window.

what would it be? will it be the bad EACV??? cheez

that sounds like the IACV, when it gets dirty after some time, usualy on older models this can happen.

check this thread on how to clean it!

so u mean it will be fixed after the EACV clean? is that anything about the fast idle valve?

give your IACV a clean and that will answer your question as to weather it does or not, the IACV should be cleaned regularly anyway :)

While your there clean the throttle body including the blade

[altong0840]

[clutch]

the throttle body blade is the flap that opens and closes allowing air to pass through, refer to this thread on how to clean :D

but i can't find where is the blade locate, i don't have any things looks similar as the pic u show me in the web......

you have to take off the airbox induction pipe, and then you will see it inside the throttle body which is attached to the intake manifold, follow the steps in that thread and you will find it.

[clutch]

can you take a photo of your intake manifold of how it looks now?

[altong0840]

it is lack of space to take the photo on the blade but i cleaned it and it shinny and perfect clean already~

as i called to the honda service department they advised me it is something wrong with about the choke, but not sure wt it is~

[酸菜炖肉]

automatic choke。

[clutch]

ok not sure about the choke, if its the same car as mine and its doing the same thing as mine, then its the IACV, but perhaps someone else on here knows more of the situation!

[altong0840]

i went to honda dealer and they show me these two pichttp://photos-b.ak.fbcdn.net/hphotos-ak-snc1/hs184.snc1/6140_121619704396_637234396_2409073_162780_n.jpg

they told me it should be the part they marked on the pics have the problem

they call it "wax choke" or wax valve ( can't remember~~)

it need to be tune or replace
