Symptoms

  • Engine hesitates and jerks when accelerating hard
  • Flashing EML light during misfire
  • Rough, lumpy idle
  • P0301-P0304 fault codes

Root Cause

The insulation inside the pencil coil breaks down due to engine heat. The spark then jumps to the cylinder head instead of crossing the spark plug gap.

How To Fix

  1. Read OBD codes to identify which cylinder is misfiring (e.g., P0302 = Cyl 2).
  2. Swap the coil pack to another cylinder and re-read codes to confirm the coil is at fault.
  3. Replace coil pack (£30-60 each).
  4. Advised to replace spark plugs at the same time.

Other Faults on This Variant

Coolant Loss and Head Gasket Failure

Severe
2006-201460,000–120,000 miles£400–£700

The Z12XE and Z12XEP 1.2-litre petrol engine in the Corsa D is known for coolant loss. In many cases this escalates to head gasket failure if not caught early.

Oil Pressure Switch Leak

Moderate
2006-201440,000–80,000 miles£10–£50

The oil pressure switch frequently fails internally, leaking engine oil directly into the electrical wiring loom.

Heater Blower Resistor Failure

Minor
2006-201430,000–90,000 miles£20–£50

The interior heater blower motor only works on speed setting 4. Settings 1, 2, and 3 are completely dead.
