Technical Hunting idle and no power pulling away

[jonjg]

Hello. Last couple of days the 1 fiat has decided to start hunting on idle and pulling away. Very difficult to drive. Changed fuel filter but made no difference. I did change the fuel filter the other month while changing the whole exhaust and giving it a complete service . Wondering whether it is dodgy fuel?
I say this because my other cinq decided to do exactly the same thing the other day. Changed the filter and seems to be ok (though can't test as it's off the road until I find a replacement radiator hose bleed).

It can't be a strange coincidence for both to start behaving exactly the same?

Checked on iawscan2 but no fault issues at all. Is it possible for the red sensor (don't know what it is) in the air box to get dirty?

I've attached some iawscan readings if anyone can help.

For those who have this issue. After cleaning the throttle body and Idle speed control valve, turned out to be the MAP sensor. Swapped with the one off another cinq and ran fine. Bizarre as it was a new map sensor from about 2 months ago. Hopefully this helps someone with the same issue.
