SOURCE: idling problem when ac turned on honda civic lxi 1999

Hi,

To my knowledge (at least in my country), some Honda Civics have a compensator solenoid the pushes on the throttle that adjust the engine's RPM to its standard idling when the A/C compressor is activated. Technically, this solenoid is nothing more but a coil and a plunger. When the compressor runs, the same relay activates this solenoid and pushes the plunger forward increasing the RPM. Pls check/clean/adjust/replace as deemed fit and necessary.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

SOURCE: how to dismantle console box of honda civic 2008

1.
Alright, let's just jump right into it. Get down and low and at the front of your center console you'll find two clips holding it in. There's one on the driver's side and one on the passenger side.
Okay so now how the *#$@ do I remove those clips? If you pull they don't come out...and if you pry you'll just scratch your console. Here's how: Look carefully and you'll see the center is a little circle. Gentley push it in...voila..off it pops. Repeat this for the other side.
2.
Alright now it's time to head to the back. You should recline your seats all the way forward and slide them up front. This will give you plenty of room to work. Get down low and you'll see a screw holding the back in -- once again you'll find it on both sides.
Simply take your Phillips head screwdriver to the ****** and unscrew it on both sides.
3.
Look carefully and you're going to see that the top of your center console is comprised of two pieces. One that stretches from the front of the console to just behind the shift boot. The second piece stretches from there to the back of the console.
The second piece is what we're going to remove. Here's how to do it. It's only held down by a few clips so all you need to do is pry it up. So whip out your flat head screw driver, or other prying device along with a cloth to prevent your crazy @$$ from prying up the plastic too. Start and the back and pry it up.
4.
You can theoretically now just pull the whole thing straight up. However what I found to be easier was to pry up one side and get your fingers underneath then pull from left to right (or vice versa) to pop off the front clips. The front clips tend to be in stiffer than the ones around the side and rear.
*POP* The entire center piece should now be free!
5.
Now you're able to lift the piece straight up.
Simply slide the piece up and forward taking care not to scratch anything
6.
Alright you'll probably discover you can't quite get it past the brake lever.
Yup...excellent deduction Sherlock..the gear shifter seems to be in the way.
7.
Alright time to move out of the way Mister Gear Shifter
Slide that baby into 1st gear (Make sure you didn't lower your hand brake!!!)
8.
It's free! Now you have room to work!
Okay now that the gear shift is in first...you have room to carefully slide the piece forward and out without scratching anything.
So now that you have the rear piece off, you want to remove the front piece right?
Well as you can see here, all that's holding it in place are these two screws on this panel.
Take your mighty Phillips head screwdriver and go buck-wild on those two screws
You've now successfully removed everything that's been holding the center console down.You should now be able to slide the center console back and forth.
There you should be able to remove it now..and you should see this

04 Honda Accord. 3000 rpm idle

I might be wrong but if it does have idle air control should be suspected. If you turn a/c on with engine running, one fan should turn on. Check for power at that fan first.
