Hmmmmm....

I have a '97 850 non-turbo with 108K miles. CEL just came on, pulled the code (PO142 - Running Rich). Posted at Volvospeed and narrowed the issue down to either a vacuum leak, bad fuel regulator, or bad front 02 sensor.

Now you've got me thinking about the coolant temp sensor. I just replaced my thermostat, I'm wondering if the CT sensor is generating a rich condition and causing the code. Has anybody pulled the same code and had a similar experience?
