Your problem is related to the idle-up which kicks in when your a/c switches on.

Have this checked by an a/c technician.

Hope this helps.

Honda crx with auto transmission idles roughly in drive or reverse. AC on makes it worse.


There are two coolant lines that connect to this Honda IAC to help quiet the operation of the valve. The part number for a OBDI 1992-1995 Honda Civic Idle Air Controller is 36450-P28-A01. While the OBDII version of this valve is 36450-P2J-J01, and the two units are very similar in design and execution. The EACV or Electronic Air Control Valve is a big part of maintaining your Honda Civic idle. If you've checked your IAC and your Honda still suffers from a surging idle, check your FITV. This Honda Idle Air Controller or IAC is under the throttle body and incorporates into the throttle body passages o locate your Fast Idle Thermo Valve, remove the intake snorkel and locate the FITV beneath your throttle body opening. If your SOHC engine is still having problems, check our guides above on how to check your FITV as well as your IAC. To check this operation, remove your air intake pipe and use your fingers to plug the passages in the lower left hand corner of your throttle body opening. If your idle surge does not go away, unplug your Idle Air Control valve and if that stops your idle surge, your IACV must be replaced. Follow our instructions on how to replace your Honda Civic Idle Air Control Valve. Need to raise your Honda Civic idle or having problems maintaining idle? You can adjust the base idle by unscrewing or screwing in the Idle screw on your throttle body. This screw allows air to bleed into the passages on the backside of your throttle body, as shown above. To learn how to adjust Honda Civic idle speed, you will not need to remove anything. With a standard screwdriver, simply locate your throttle body and Idle screw.

Where the idle screw located


There is no idle adjustment screw on this engine, which is normal for EFI engines. The idle is controlled by the car's computer. It does this by controlling the Idle Air Control - IAC - valve, which should be checked in your case. See here p271

There is a throttle stop screw, not the same, on the throttle body, which you may be thinking of, p263. This does not directly control idle speed.


Also the A/C, if any, can affect the idle if the A/C idle-up switch has failed. If testing this switch, do so when the engine is hot, as that is when they fail. See p295

Really rough engine idle at cold start up,, reving the engine seems to smooth it out,,,,


Some causes about rought idle could be:
- Valve adjustment
- Incorrect ignition timing,
- Vacuum leaks
- Bad ignition wires (Test w/ ohmmeter)
- Incorrect idle speed
- Cold Start Injector always "ON" (Revised injector time switch avail.)

A source of rough idle in EFI engines is air leaks or vacum leaks these leaks will upset the fuel mixture without triggering any codes. A bad oxigen sensor will also cause a rough idle, but you should see a code for it ( I think is number 5, but check it).

A good place to start would be an inspection of the spark plugs, plug wires, ignition timing, and idle speed. Next would be valve adjustment. Don't overlook the simple things.

Hope this helps, keep us updated and just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa.

Honda civic 2000- idle speed is high even in park or neutral


Check your coolant level. The Idle air control valve works with coolant in the system and will produce high idle it there is very little coolant. Also check to see if there are any vacuum lines disconnected. They can also cause the high idle.

Idle Adjustment Screw Location on 96 Civic


your idle can not be manually adjusted. it is controled by the ecm via the throttle position sensor on the throttle body(tps). you have to have a diagnostic scanner to interface with the ecm to adjust the idle. most service shops have this equipment
