Greetings to my fellow S40 owners. I am glad to found this forum on time. I guess it would save me lots of money and frustration. I own a 1998 S40 2.0i that I was gifted by a cousin with 141,000 miles on it. The car starts fine and will run for up 2 miles and then lose power. It never stalls just won't move. If I shut it off and immediately restart it, it will run fine again for another 2 miles and so on and so on. When I depress the gas, the car hesitates severely, backfires a few times. If I back off the gas at times I can usually accelerate very slowly and once I get up to speed it is ok.
