Hi guys.

Im a pround owner of a Persona B-line. Got some problrm with the car. After the 10,000 km service, the engine started to make noise. It’s kind of wind sound (like water boiling sound) when the speed reach 110 km/hour. Not only that, when the vehicle slow down after the ‘high-speed’ run (just to describe this scenario..ahem), the sound can be heard clearly too especially when the vehicle started to move.

Have anyone ssen this kind of problem?? My car also semm to be underpower a lot..
