What are the systems if any that you experience when the car is started cold till it reaches operating temperture while ideling and driving?

I can only tell you what I read in my Mercedes- Work Shop manuals to fine what the problem is I need to know more of what systems you have. Also how many miles on the odometer? when was the last time an o2 sensor was changed?

I am not an expert but we share the same year and engine. I would be more than happy to look up some information if you give me some vital signs to go by.
