Upon inspection, the technician will find medium to high misfire counts and the symptom always occurs on one or two cylinders and goes away when the engine warms up. Now, a misfire or rough idle isn’t that uncommon in the grand scheme of things, but in this case it’s what’s causing them that’s unusual.
