Map sensor question (to add to the list )

Thanks for looking at yet another one of my clutching at straws questions re punto maintenance , if I unplug the map sensor on my 1.2l petrol punto and the engine runs smooth (which it did) and then I plug it back in again and my rough idle returns does that more than likely mean that the map sensor need replacing or cleaning ? , I know it sounds obvious but could It also be hiding something else and unplugging the sensor hides the real problem ?

When you unplug your MAP sensor the car will run on 'default' settings.

I had a problem with my car (not a Punto..) whereby it was kangarooing, jerking and cutting out but would restart immediately.

I did the same as you did - unplugged the MAP sensor and found that the car ran 'okayish'. Changing the MAP cured the erratic running altogether.
