Short answer: A Ghibli with a flashing check engine light is actively misfiring. Owners reported rough idle, stalls, and foul exhaust smells. Park it—continued driving can wreck the catalytic converters.
Symptom: Flashing CEL, rough idle, stalling, raw fuel or rotten-egg exhaust smell, or white/gray smoke.
What to check first
- Stop driving while the CEL is flashing.
- Save the misfire codes.
- Check for vacuum leaks and coil/plug condition.
- Tow to a Maserati specialist if it will not run smoothly.
Likely causes
- Ignition or fuel misfire on one or more cylinders. Flashing CEL plus rough running means raw fuel is likely leaving a cylinder. Coils, plugs, and injectors are first checks.
- Vacuum leak or turbo/wastegate issue. Owners with SQ4 models also chase boost and vacuum leaks when misfires stack up.
- Catalytic converter damage from continued driving. Driving on a flashing CEL can overheat and destroy cats—expensive on a Maserati.
What it usually costs
Owners were mid-diagnosis; ignition parts are cheaper than cats or turbos.
Is it safe to keep driving?
No while the light flashes or the car stalls. Tow it.
DIY or shop?
Basic scanning and plug/coil swaps can be DIY; most Ghibli work is specialist.
