Checking the ignition timing

Check idle speed

Checking the composition of the mixture at idle

NOTE

In normal cases, the ignition timing is not adjustable. To check the ignition timing requires the presence of a specialist unit and WDS or an analogue thereof.

Turn off electricity consumers and warm up the engine.

Start the engine.

Keep the engine speed of about 3000 ^min -1 until the fans start to run the cooling system.

Release the accelerator pedal.

Wait for the shutdown cooling fans.

Check the ignition timing (WDS: PID SPARKADV) norm, using the WDS or equivalent.

Ignition timing is about 10 ?� before TDC.

Make sure that the ignition timing is increased simultaneously with the engine speed.
