ok...p1238, head scratching time...

Yep, got the lovely error p1238 on fiatscan.

On the read outs desired air is 290mg, actual air is 481 mg on tick over of course.....

Now, checked and cleaned all sensors relating to this, checked all hoses, cleaned all connections.

Running of the car is fine. All the power, no smoke, averaged 62mpg on a long run yesterday....

I'm officially stumped. I know the sensor itself could be knackered, but its responding and giving readings and recognizing there's an issue with the difference in air quantity so not entirely convinced its the actual MAF. Beginning to regret buying an Alfa now...sorry to say it.

Anyway, if any one has ever found themselves in the same boat, i'e same code but checked and cleaned everything, hoses sensors egr valves etc and sorted it, please let me in on your secret!?!?!

Love to all....
