IGNITION AND INJECTION

17 - 86

ALP 3

IDLING PROBLEMS (unstable idling)

RECOMMENDATIONS Do not consult this diagnostic but before performing a complete

checking by means of the CLIP tester.

Check if there is petrol in the fuel tank (fuel indicator failure)
Check if the vehicle is supplied with adequate fuel

Check that supply circuit hoses are not broken (especially further to a dismounting)
Check the condition of the fuel filter
Check the condition of the fuel tank
Check that fuel tank aeration is taking place.

Check the connection and the condition of the idling regulator connector.
Replace the connector if necessary.

Check the motor of the idling regulator
In order to unblock it, you may slightly hit it.

Disconnect the connection hose between the canister purging valve and the intake manifold.
Clamp the connection hose in order to stop the air passing.
If there are no more disturbances, the cause is the canister purging valve.

Check the spark plugs and ignition coil condition
Check that these elements are specific to that vehicle.

Check that the exhaust route is not clogged and the catalyst is not clogged.

Check, by means of the oil dipstick, that oil level is not too high.

Check for lack of sealing at servo-brake (noise).

Check the intake manifold condition

Check if the valve body is not clogged

Check the engine compressions.

Check the engine flywheel condition

Check the distribution setting on.

AFTER

Perform a checking by means of the CLIP tester.

REPARATION

Failure locating algorithm
