2.0 Zetec had a plugged PCV hose and caused blow by to allow oil into the air box. It developed an occasional engine miss due to this. Fixed the line cleaned it all up but engine miss still persists. Changed the plugs, checked the wires and changed the fuel filter. Any idea?

Have it scanned for free at autozone or the like. You'll find out for free where the miss is.
