I have a 95 850 Turbo w 108K miles. I am about to take in to the local Volvo shop but wanted to ask what could be causing my car to stink. This morning was about 60 degrees and I could see a very light smoke from the tail while it idled. I have driven behind the car and do not see any clouds or anything like that, any ideas. The car seems to be struggling while idle. Any thoughts would be appreciated.

Sounds like your catylitic converter. Lack of power and smelly car usually equate to a bad cat.

2 850:

this sound like catalytic problem. try changing gas stations for now. try brand names. also check if you have the check engine light on and if so, try to read the code and determine if it is related to the O2 sensors.

beyond that you may need tune-up/adjustment to make sure the engine is not running rich as this would damage the catalytic converter.

I am smelling oil burning on my 94 850 Turbo. I also can not tell where it is coming from. Please post your findings.
