where is the IACV located in a 92 hatch?

 

Back of the intake manifold, of course


Number 12

 

thanks for the diagram

so to remove it the bolts come out of the back?

 

Yes, you remove 2 M8 (12mm hex) bolts, and it will come off the manifold.
Be careful not to lose the rubber gasket - I suggest removing the gasket asap, once the iacv is off and putting it somewhere safe - dont forget to put it back.
There are also 2 coolant lines, and an electrical plug.

 

should i disconnect the battery when i do this? and obviously gotta disconnect the 2 coolant lines

 

quick bump

 

why bump so fast??

no need to disconnect the battery - as long as the car is off while you disconnect, nothing will happen

 

Just keep the IACV plug away from any spilling coolant when you pop those hoses off...

This is where some cups and rags come in handy

 

thanks for the help...will the coolant lines start bleeding right away when i take the hoses off?

 

nahh just keep them pointing up and you will have minimal fluid loss

 

i cleaned out the IACV and car STILL idles like ****, almost stalled today......i have no idea what it is now. any ideas?

 

what is it doing?
low, irratic, what?

 

its really low...around 250-500 rpms, and when i turn on the AC it goes even lower

 

Any CEL codes?

 

what type of pins do i have to insert?

 

Have you messed with the idle adjustment screw at all?
If its too far in, go about the proper procedure and back it out to reset the idle to the proper speed

o ok thanks i will try that, i adjusted the idle screw like a year ago

 

to check the CEL, what kind of pins do i have to insert?

 

a bent paper clipinto a horseshoe connecting both pins in the plug is your best bet

The IAC-motor could be shot. Try swapping out with a known good unit if you have a friend with a similar motor. The one on my B18C swap was stuck closed when I first bought the swap making it really difficult to start. After I cleaned it, it started working again, but it doesn't quite react fast enough engine is in high idle mode (warm-up). It causes the idle to pulse a little when the car is first started. It does works fine once up to temp though.

 

hmm, the IACV is the same for 92-95 civics right....i think 1 of my friends has a 92 civic sedan beater than hes willing to help me out with, but otherwise how would i know if the IACV is shot for sure?
