Id really love some assistance in locating my IACV if possible.

I have a Automatic 2002 Honda Civic Ferio (1500cc vtech), with 140,000 km, having trouble finding much on this model, seems to be quite rare, last time I had a full service I asked the mechanic to clean the IACV and he had no idea what I was talking about, tried to explain, and he still didn't know : /

I think this is the model: http://www.cars-directory.net/specs/...2002_10/12460/

Basically my car has lumpy/fluctuating idle, once it warms up it should sit at about 750rpm, however it normally sits at 650-700, and sometimes drops to 600. When its at 600 and the light goes green for example, you put your foot down and its like "stuck in neutral almost", revs go up to say, 1000-1500, then it finally engages gear, and lurches a bit. This only ever happens trying to take off from 600 or so RPM.

Also if I need to break hard, afterward the car drops way down to like 500rpm, shudders, then recovers to say 900, then drops to 550, shudders, and recovers to 850... does a few cycles of this until its around 650-700 again.

Hope this is making sense!

Ive attached a picture of my engine, which is a D15B Vtech, as I havnt seen one similar yet. Can anyone help point out my IACV?

The red circle is where is says "D15B"

The yellow circle is the air filter

The green circle is a compartment with about 8 screws, I have opened it thinking maybe the IACV was inside it (probably silly me), but its another filter that's about 15cm x 15 cm square on the left hand side of the compartment, with the right hand side being slightly triangular shape and empty.

I can't for the life of me find something that looks like the IACV in the OP. Is someone able to edit my picture and point where to look, and perhaps even point me to some existing instructions related to my model of engine?

Thanks!

Edit: only had the car 1 year, so limited paper work on whats been done recently.

-Replaced oxygen sensor
-Full (the works) service
-Replaced transmission fluid

First, the IACV is under the airbox on the passenger side of the throttlebody. To remove the airbox you'll need to remove the 2 bolts and disconnect the vacuum line to the valve cover. Then, from the drivers side, take a long phillips head and loosen the large clamp holding the airbox to the throttlebody. You'll also need a really long phillips head to get the IACV off.

Second, I had the same symptoms and it was a bad brake booster.

Thanks a lot for the reply, i'll do some research into the brake booster, but in the mean time try to clean my IACV.

So firstly, I am in New Zealand (and notice you are in US), and our drivers side and passengers side are the opposite!

So if we go by my picture, are you saying its under the airbox circled in yellow?

And then with the long phillips head to loosen the clamp, would that be on the left or right side of the image?

Cheers

Under the airbox in the green circle.

You should be able to reach the clamp with a long phillips head from you're passenger side.
