2009 Saab 9-3T Cold, rough idle
I have about 57K miles on the car and it has always ran great. It is hitting 20 degrees F here in Philadelphia and the car has idled rough upon initial start up. The other day, it had a harder time even starting.
I read a lot about valve issues in the earlier models and it looks like the service bulletin was updated to include years 2009-2011.... oh no. The symptoms are similar to what I am experiencing.
Are there any techs out there that have other ideas? I will probably do a compression test over the weekend to see whether all 4 cylinders have good/same compression.
Other ideas? Other experiences with insight?
