Hello 84andrey2002

You may need to set the warm idle speed.
If your civic is a Canadian vehicle, the parking brake must be applied before proceeding with any adjustments.
1. Make sure the heater is in the full cold position and all electrical consumers are in the off position, such as headlights, defrosters, climate control fans, and other electrical accessories.
2. Start the engine and hold the engine speed to 3,000 rpm with the transmission in Park or Neutral, until the radiator cooling fan comes on, then let the engine idle.
3. Connect a tachometer or the Honda PGM Testing Assembly.
4. 1.6L models:
1. Disconnect the round 2 pin electrical connector from the Idle Air Control (IAC) valve.
5. If the engine stalls, restart pressing the accelerator, hold the engine speed at 1,000 rpm, and slowly release the gas pedal until the engine idles.
6. Check the idle speed making sure all electrical accessories are turned off, with the transmission in Park or Neutral.
7. The idle speed should be 500-600 rpm
8. If the idle speed must be adjusted, do not turn the adjusting screw located at the top left of the throttle body inlet side more than 1 / 4 th of a turn a minute. Make sure no electrical accessories are operating when checking or adjusting the engine idle speed.
1. Once the correct test procedure idle speed is attained, turn the ignition switch to the off position.
2. Reconnect the round 2 pin electrical connector to the Idle Air Control (IAC) valve.
3. Remove the BACK UP (RADIO) 7.5 Amp fuse located in the under-hood fuse/relay box for 10 seconds to reset the Powertrain Control Module (PCM).
