The fault is probably due to a component that can only affect this cylinder:
– check the cylinder 1 pencil coil,
– check the condition and conformity of the spark plugs,
– check the cylinder 1 injector
If everything is in order, check the same components on cylinder 4 (to cover a possible
cylinder recognition error).
The fault is probably due to a component that affects a pair of cylinders:
– check the ignition coil circuit concerned (apply the interpretation of fault DF361
Ignition coil control 1-4),
– check the condition and conformity of the spark plugs.
The fault is probably due to a component affecting all the cylinders:
– check that the correct fuel is being used,
– check the condition and conformity of the spark plugs.
If the fault is still present, carry out the following checks:
– check the flywheel sensor,
– check the condition and cleanliness of the flywheel,
– check the flywheel sensor mounting,
– check the sensor/flywheel air gap,
– check the cylinder compressions,
– check the complete fuel system (see MR 364 or 370 Mechanics, 13A, Fuel supply, Petrol supply system),
– check the complete ignition system (see MR 364 or 370 Mechanics, 17A, Ignition, Spark plugs),
– check the hydraulic tappets if there is camshaft noise (see MR 364 or 370 Mechanics, 11A, Top and front of
engine).
If the fault is still present, deal with the other faults then proceed with the conformity check.
