Your ignition coils convert battery voltage into the high-voltage current needed to fire your spark plugs — making them essential for smooth starts, fuel efficiency, and consistent power. In this video, Circle & Square Auto Care explains how our technicians diagnose and replace faulty ignition coils to restore reliable performance and prevent misfires.

When an ignition coil fails, it can cause rough idling, loss of power, poor fuel economy, or an illuminated check engine light. Our ASE-certified technicians use advanced diagnostic tools to test coil output, inspect wiring connections, and confirm spark delivery to each cylinder.

If replacement is necessary, we install high-quality OEM ignition coils and check spark plugs and related components as part of the comprehensive process outlined in our engine performance and maintenance service. This ensures balanced ignition and long-term reliability.

At Circle & Square Auto Care, we take precision and dependability seriously — delivering expert ignition system repairs that keep your vehicle starting strong and running efficiently.
