Possible Fault Causes
Ignition or injection miss, defective spark plug, defective wiring harness and
plugs/contacts, induction mixture problem, defective ignition coil, defective injection
valve, VANOS fault
Repair procedures (plant/service)
1. If problem is present with mixture, VANOS, lambda control/oxygen sensor, camshaft
control, injection valves, then repair these faults first. 2. Spark plug visual
inspection (cracked ceramic insulator, black electrodes, electrode gap, etc.), replace
as indicated, 3. Wiring harness electrical check, check contacts (corrosion, insulation

damage) 4. Check ignition coil for corrosion, cracks, interchange coils between
cylinders as indicated, conduct road test with full acceleration and note whether fault
in fault memory migrates, replace ignition coil as indicated
