OK,I've changed the spark plugs,wires,intake manifold gaskets.Added fuel injector cleaner,and cleaned the throttle body.Searched for vacuum leaks.EGR holds vacuum ok.
The car runs perfectly smooth,except on a start up and especially when I turn on the AC.-Then I get a sporatic misfire.Only code thus far was once last week when it only indicated "misfire within first 1000 rpm."Nothing this week.
