Has anyone experienced this problem?

Any ideas on a cure? MAF sensor - Throttle pots - WHY ?

I've cleaned out the hose leading from the inlet manifold to the MAF sensor and found it is clear.

The engine will always fire up, but sometimes it will have difficulty keeping the revs at its normal 800rpm.
The engine tries to idle at below 500rpm then die on me. Playing with the loud pedal has little or no effect. She will always fire up and after a couple of tries the problem will clear, and then drive beautifully all day until it is switched off.
If I'm lucky it will fire up as normal, but sometimes it will resort to this rough idle on start up.
