Intermittently, my
engine will climb a couple of hundred revs from
cruise power for 10-15 seconds, then return. Usually not until the
engine is warm, and very intermittently. On a recent
cruise, didn't do it at all one day, once an hour or so the next.
Any clues on what to look for? One crew suggested a
fuel system air leak, but I would think it'd hesitate instead of over revving......
