Check Engine Light Flashing

The check engine light flashing on a 2011 Ford Ranger is a severity indicator — it usually points to an active misfire that can damage the catalytic converter and reduce engine reliability if you continue to drive. When the light flashes, you should stop driving as soon as it is safe and have the vehicle inspected immediately. At Larry H.

Choosing our dealership often costs less than independent shops because precise diagnostics prevent repeat visits, and OEM parts deliver predictable durability. We also explain repair options, warranty coverage, and immediate versus long-term benefits so you can make an informed decision.
