This answer was rated:

my Peugeot 2ltr coupe petrol engine year 2000 cuts out in idle revs when approaching roudabouts and juctions regularly. revs make a dramatic dip. there was a period when the revs would go up and down when no throttle was applied. this hasnt happened recently. no issues with cutting out other than low revs

hi mike.ive never seen any warning lights come on with this problem. there was nothing showing when I was connected to diagnostic machine either. cant think of any more info that could help.

The issue that you are describing is consistent with a failing mass air flow sensor,the mass air flow sensor measures the fuel /air mixture and when failing results in your issue.
