Rough cold start...
The car sat in the cold garage for a few days over Christmas. Today I went to start it and the engine was slow to turn over, then it fired up, but it was very rough and much louder for about 3 or 4 seconds. In fact the entire shook, but then it smoothed out and sounded/ran fine. No codes or check engine lights.
I've been through a winter already so I've started the car in the cold before after it sat, but never did this before.
Has anyone experienced anything similar?
