This is one reason why your car might be hesitating when you are first
accelerating or when you are braking and the idles drop*you might have
a dirty IAC valve. Its not hard to clean yourself, I rate it a 1 out
of 10.
Disclaimer: I'm not responsible for any damages or broken limbs or
anything wrong happening to your car when you do this*this is exactly what
I did and it worked for me. BTW, this was done on a '92 accord ex.
On a side note, I didn't have my camera with me when I first took it
off so I have no pics of the IAC Valve dirty on after I cleaned it but
I'll describe it as much as possible.
1. Disconnect the negative cable on the battery and then disconnect
the grey plug from the IAC valve
2. Disconnect the hose the leads form the PCV valve to the intake
manifold to give you more room to work on.
3. Remove the 2 12mm bolts that connect the IAC valve to the intake
manifold.
4. Disconnect the 2 small hoses that are connected to the IAC valve.
Chances are that they haven't been taken off ever so they're going to
be hard to remove. Keep at it though and some wiggling and prying will
get them off. Once you take them off some coolant will leak out, just
wipe it up with the rag and you're good to go.
5. Now you will have the IAC valve all alone and off the car. Look at
the back of it and you will see 2 holes, one with a screen and the
other with out a screen*most likely they will be black covered with carbon
deposits. This is why your car has been stuttering and running bad
because there isn't any way air can get in to control the idle of your
car.
6. Grab the throttle body cleaner (I used carb cleaner because they
have run out of throttle body cleaner but it serves the same purpose) and
spray it on the 2 holes to clean away all the black dirt. You know
youre done when the screen is silver (the hole on the right) and the
diaphragm (hole on the left) is white and not black. I kept on spraying a
bit until the liquid that was coming out of the holes looked clean and
not dirty.
7. Now go back to your car and clean off the area with some more
throttle body cleaner. Voila, you're done with the cleaning.
8. Installation is the reverse of removal. Make sure all your hoses
are tight and to plug in the IAC valve or else you'll get a CEL.
Connect the battery and start her up making sure the hoses aren't leaking
and everything sounds normal.
9. If the idle is off a bit, you could adjust by turning the idle
adjust screw below the throttle body mine was fine so I didn't have to do
that.
Good luck guys, hope this helps.
