Idle speed adjustment (Mazda Capella GD)

Based on the automatic fuel-air mixture compensation function implemented in the engine control unit, there is no need to monitor or adjust the fuel mixture, meaning that only the idle speed needs to be checked and/or adjusted. A prerequisite for normal idling is good engine condition.

Turn off all current collectors.

Start the engine in warm mode and let it run for three minutes at 2500–3000 rpm.

Check ignition and adjust if necessary.

Pull the plug connection out of the air bleed valve.

Determine the idle speed on the RPM chip meter. It should be 800 rpm with a built-in step gearbox or 900 rpm with a built-in automatic gearbox (position "P"), with a tolerance of +50 rpm.

If the number of revolutions does not match, remove the sealed cap and use a screwdriver to adjust the air adjustment bolt as shown in Figure 143.



Finally, install a new sealed cap.
