hi
I have a 2001 S60 2.4T
I am having problem with this car.
I always warming up the car before I dirve. but car's rpm always around 500-700 sometimes it even shutting down and I just realized it spend gas more than it used to. I am guessing this is about oxygen filter but I am not sure. please help me about this situation.
thanks

Hello,

I had a similar situation that you described with my S60. I took it to the dealership and they replaced the throttle body and upgraded the firmware. Problem resolved. Fortunately my car was under dealer warranty.
