Hi All,

I have been chasing a error on my soon to be fiat panda donor engien.
When first started from cold it hunts badly, then it flattens out.

I have cleaned the TB, new plugs and ICV. I noted the error light on and my code reader arrived this morning

I have a map error, but looking at the readings:

Im reading a manifold pressure.

The error persists, even after clearing. Is this likely the sensor or a wiring fault?

Thanks very much, as soon as I fix this I can crack on!
 
Loose or unconnected MAP sensor plug? Had a problem of this sort several times now...

The fact that is shows MAP values does not have to mean much, it might be some recovery value.
 
An update for any one who has an injector light, VERY bad starting and then a hunting until warm. It was a dead map sensor.

Replaced the map sensor this morning and started it, light went out, back to perfect tick over cold and warm.
