Dears,
I newly bought a Volvo xc60 mod 2009 with about 65000 miles on it.
Everything was running smoothly until the Check Engine light popped up.
As per the service centre, it was related to the catalytic converter and it didnot appear again after adding some fuel cleaner to the fuel tank.
Now, the Check Engine light is off but I am facing another error.
whenever I start the car, the engine sound is rough and RPM is not stable. Even when accelerating, the engine is rough but the acceleration is very poor, as if the gas pedal is not working or delivering fuel.
Please advise.

 

you'd need to have a tech look at live data from the computers to see what's going on. There's too many possible causes for a rough idle and low power. Fuel delivery (ie fuel pressure), air mix, weak spark are all in play here.
