I have a 2000 volvo S40 just get it as a gift for my b-day its awsome but needs some work done. For some reason the car isnt Breathing I know because the car is heisting and it seems like there was a clog but I check every hose and didn’t find anything I think it might be the Mass flow sensor. How can I know if it’s the mass flow sensor besides buying a new one, any help would be appreciated. Look forward to meeting many Volvo owners.
