What makes my car start with rough idle at first?

Yes I use oil and coolant and do not have significant leaks but may take plugs out and clean or replace them.I did notice the top of a plug or two are black don't know if they are supposed to be I assume they should be silver I just noticed when taking plug wire off. My mechanic suggested I take brake cleaner and clean mass airflow where it connects to engine?

I think new plugs will help.I see what you are saying about coolant and oil ASEMaster6371.I think it probably is in the ignition maybe but I am only guessing. Since I had a new ignition control module put in I am discounting this but it could be bad.I do have a warranty on this for 1 year. So I may get the same place to check it out but there is no "check engine " light coming on but can they tell me if they hook it up to the computer.I think I will try new plugs 1st.I have maintained this car for years and runs great so I will keep on digging.
