Hello All,

Looking for some assistance before going to repair shop. My wife has a 2013 countryman s that has a rough idle at startup and then levels out after driving for about 10 to 15 minutes. I have completed the following work already and not sure where else to consider as possible part of the issue:
1 Replaced High Pressure Fuel Pump
2. Replaced all Spark Plugs
3. Replaced all Coil packs (checked them all and running at 8 ohms)
4. Replaced mass air flow sensor
5, Replaced PCV valve cover (old cover was brittle and slight tear...was hoping this would do the trick, but no luck)
6. No visible oil leaks around valve cover

Car is not throwing any codes even during rough idle startup. Any suggestions of guidance would be most appreciate before I go and drop a few hundred dollars for a evaluation.
Thanks,
Steve
