2001 Ford Focus Strong intermittent miss
Strong intermittent miss
What is your question?
Sets both a 401 and 402 code along with an intermittent 302 (misfire in #2 cyl) Changed EGR position switch and has changed problem, now an intermittent strong miss? Changed plugs and wires as well.
might have multiple concerns, check cylinder copression just to rule out mechanical concern, check fuel injector harness and operation on the affected cylinder. i would also inspect the spark plug on #2 and see what kind of burn pattern it has
