Check Engine Light Flashing

A flashing check engine light on a 2024 Ram Promaster Cargo Van is an urgent warning that the engine is misfiring and unburned fuel may be entering the exhaust system. This can quickly overheat and damage the catalytic converter, leading to far higher repair costs and potential safety issues. At Larry H. Miller Chrysler Jeep Dodge Ram Boise, our first priority is safety and fast, accurate diagnosis: we inspect ignition components, fuel delivery, and emission controls using OEM-level scanners. Because our technicians are factory-trained, they identify whether the flashing light is caused by an ignition coil, spark plug, injector, or other system failure and recommend the most economical repair path. We emphasize transparent pricing that often costs less than independent shops when you factor in correct diagnostics, OEM parts, and warranty protection. Check our service specials and schedule appointment to get immediate attention and avoid escalation of damage.
