Check Engine Light Flashing

A flashing check engine light on a 2025 Toyota GR86 signals a potentially serious condition—often an active misfire that can damage the catalytic converter if driven hard.

We perform rapid diagnostics with Toyota-approved equipment, identify misfire causes (ignition coils, spark plugs, fuel delivery, or sensor faults), and present clear repair options. Because we use OEM parts and factory procedures, repairs preserve performance, safety, and resale value. We also explain warranty coverage and how completing repairs at a certified dealership protects that coverage.
