In colder weather the car has a very rough idle until it begins to warm up somewhat, how do I troubleshoot this; ie: what steps can I follow to eliminate and/or identify the source/cause of this malfunction?
The car might be in need of an inspection II
Replacement of the spark plugs, adjusting the valves, inspecting the ignition components, oil and filters.
Have these issues been addressed? When was the last insp II performed?
