Common Issues This Part May Address

  • Engine misfire caused by worn rotor contact surfaces
  • Hard starting related to weak or inconsistent spark distribution
  • Rough idle from degraded distributor ignition transfer
  • Intermittent spark delivery in distributor-equipped engines
  • Ignition performance loss from rotor wear or damage

Installation Notes and Tips

Verify distributor housing style and engine application before installation. Compare the old rotor to the replacement for fit, terminal alignment, and mounting style, and inspect the distributor cap, cap terminals, and ignition components for wear while the distributor is open. For 1989 Pontiac LeMans applications, the catalog notes a 72mm diameter housing and vendor reference D450.

Quality Assurance

Facet ignition components are cataloged for specific vehicle applications and should be matched to the exact year, make, and model listed in the fitment data. Confirm the distributor type and application details before service.
