Emissions

Failed the the test on emissions high idle.

Co 0.63vol%. Was above 0.20%.

Any idea what can Be done.

Mr Benevolent

Thrash it on the drive back to the test centre. A hot engine gives a lower CO reading.

Assuming there is no misfire at high idle, I'd get someone with a scanner to see what way the O2 sensor is switching. If it is not switching properly then get it replaced, preferably with a genuine one.

What you can also do is swap the two O2 sensors around (pre cat and post cat) temporarily and see does that make any difference.

Also if you are changing plug or leads, get the genuine ones from Fiat. I've had none genuine plugs cause problems, and non-genuine leads usually don't have the internal ballast that the proper ones do.
