Thanks for the advise. This is my first Volvo and my first turbo in general so I'm happy about your feedback.
Its been some days now since I changed the MAF and its still running great.

Here's another follow-up: Cleaning the throttle body stopped the stalling but instead the car started idling very roughly after a longer drive. The fuel mileage was also approx 10% better than before the cleaning. When I let the car idle roughly for a while the CEL came on and gave me the P0103 and ...

The car stalled again yesterday so I tried a new angle today and cleaned the throttle body. It looked pretty bad - maybe that brings some change. I've read that somewhere that this is associated with engine stalls when idling. sIMG_0958.jpg sIMG_0960.jpg sIMG_0961.jpg sIMG_0962.jpg Let's see what ha...

Just a follow-up post. I met my mechanic friend and we checked for vacuum leaks but it all looks good. I also changed from midgrade to premium fuel and there's no stall or cel so far. Actually it runs like the devil right now (in a good way, yay!)

Cleaned and zap strapped down. No cel so far - let's see how it goes. Thanks everyone.

Oh, I see. I don't have this kind of equipment. I'll clean and tie the connector tomorrow and see if the etc comes back. Thanks for the help so far.

Mmmh, if this is the quick way to test the MAF - what would be the correct way?

Thanks for the posts. I cleaned the MAF with MAF cleaner from Canadian Tire after I got the p0103 for the first time approx two weeks ago. I'll try the "tie down" tomorrow.

Hello everybody, For a while, I'm trying to figure out if my 1998 V70 T5M (143tkm) has a bad MAF sensor. I'm not really a car person and VERY far away from being a "real" mechanic but I'm also cheap and try to see if I can figure out a problem before going to a shop or dealership. I got in...
