Thanks for all of your advice, this car is quite rare in sweden, so it is hard do get some good advice. I'm ordering a new Bosch intercooler pump, as well as a new intake air temp sensor. If anyone else have some thought as to what might be the issue, please feel free to respond, as I'm going to leave the car at a garage, and then tell them to look into it, but as this car is quite rare I think it is easier if I have a few suggestions on how to fix the issue. Thanks!
