All KE70 Corolla problems All workshop issues

Common Electrical

Ignition System Deterioration

Symptoms

Hard starting, misfires, rough running, loss of power, poor fuel economy. Engine cutting out intermittently.

Cause

The KE70 uses a points-and-condenser ignition system (early cars) or an electronic ignition system (later cars). Points pit and wear, condenser capacitors fail, the distributor cap cracks, rotor buttons burn, and high-tension leads deteriorate with age and heat.

Fix

Full ignition service: new points and condenser (if applicable, $15-25), distributor cap and rotor ($20-40), spark plugs ($15-30), and high-tension leads ($30-60).

For points-equipped cars, upgrading to an electronic ignition module (Pertronix or similar) eliminates points maintenance entirely.

Cost: $80-150 for the module.
