Hello, first posting for me. We have a 99 Vanden Plas. It is starting to get cold up here in Calgary and last night the car kicked into 'restricted performance". I checked the codes this morning and got a "running too rich" message. I erased the code and the car seems fine now. Was this just a case of the sensors figuring out how to deal with the cold air or should I be checking something out???

You may want to wait a bit more... If some sensors are going bad, it will show up. I would not worry too much.

 

Thanks 100. Still no problem as of Oct 08. Drove the car from Calgary to Whitefish and back. It ran great.

Depending on how many miles you have recorded, I'd go with replacing the O2 sensors.
