- Common causes include ignition misfires (spark plugs or coils), oxygen sensor faults, catalytic converter efficiency issues, and turbo underboost events.
- Misfires can stem from worn plugs or failing coils and degrade performance and emissions; turbo-related faults reduce power and efficiency.

2020 Alfa Romeo Stelvio Base Check Engine Light Flashing
A flashing check engine light on a 2020 Alfa Romeo Stelvio Base signals a severe misfire or another high-risk condition that can quickly damage the catalytic converter and engine internals. Driving with a flashing MIL risks overheating components, increasing emissions, and creating costly downstream repairs; stop driving as soon as safely possible and minimize throttle. Have the vehicle towed to Herb Chambers Alfa Romeo of Boston for immediate inspection. Our factory-trained technicians use OEM diagnostic tools to identify misfires, ignition faults, fuel-system problems, or turbo-related failures quickly.
