What would cause a warm engine to "pulse" at 3K rpms ?
It starts at normal idle, then, when I bring the revs up to 3K, and hold it there, the engine revs go up and down, as if I were tapping the petal.
It's not trying to stall, just a rapid increase and decrease in RPM.
The kicker is, the tach doesn't indicate the revs going up and down.
It sits on 3000 until I let off the throttle, at which point it returns to normal idle ! ???
