What It Helps Fix

  • Engine misfires caused by a weak or failing ignition coil
  • Hard starting related to inconsistent spark output
  • Rough idle from ignition breakdown under load
  • Loss of acceleration response tied to poor coil performance
  • Check engine light conditions associated with ignition system faults

Installation Notes and Tips

Verify connector style, terminal count, and mounting location before installation. This coil uses a bolt mount with one mounting hole and a female connector, so matching the original configuration is important for proper fitment on the Scion iQ. Inspect the ignition system for worn plugs, damaged connectors, or heat-related wiring issues before installing the new coil.
