Check for vacuum leak. Some fords use hard plastic vacuum pipes(hoses) that tend to break over time. This will cause a very rough idle.


If a mechanic changed your plugs, bring it back. Possible causes are a plug not gapped correctly, or a plug wire not returned to the proper location. If it was running correctly before, it should not be running bad after replacing the plugs
