Thumbs up 300SE W126 Head Gasket 1990 240,000miles

I had the head gasket replaced....oil & water were mixing e.t.c.....all OK now with oil/water suytem(full isolation & no leaks).....but engine speed starts hunting at idle once engine warmed up and driving...not good at traffic queues.....since engine stalls.....has anybody got any ideas......!!!

I have some idea that it is due to....the reduction in airflow.....causing idle switch fluctuating between closed and open contact......If anybody has an idea...please post here....for urgent fix....!!!
