Sounds like a similar problem to one I had in my 4000. I found it lay with
the idle stabilisation valve. This is a little black cylindrical thing near
the front bulkhead and at the opposite side of the engine to the radiator.
it has some concertina type tubes and an electrical connection on it.
When the symptom happens try tapping it if the fault stops then a temporary
fix is to clean it and lubricate the interior with release oil. You will
need to replace it soon.
