Quite possibly mate they are prone to dying and getting gummed up with muck from the inlet..
Also check all your vac hoses, make sure you have no air leaks.. :D

I had the same problem solved mine by cleaning the air flow meter ... Easy to remove just two clips plus the sensor cable, gave it a good spray of WD40 cleaned internals with a rag ... Mine has a stable idle now ..

a bad lambda will also cause a bad idle
