General New Cabrio 1995 1.6 - messy injectors !

[chesh]

Got a new silver cabrio next to my yellow one
It has been running pretty rough at idle and shot black smoke when accelerating.
I checked the spark plugs and it's all black.
I just see there are 2 orange injectors!

I know orange injectors came in Punto 75 MPI since having one also.
Should I change them asap?

I don't know whether you need to change them, but I have just checked and my 94 Cabrio does not have orange injectors. However, even if two are not correct, would it affect all plugs?
On another matter, you might wish to check the folding of the roof and the position of the central cross bar.
