I took my car into Alfa Workshop for a service and asked them to look at the slight misfire which it has, particularly when cold. I have replaced all plugs, coil packs, and the temperature sensor (coolant), which made little difference.
They couldn't find any fault codes and reckon it would be an injector issue, which is apparently common.
AlfaWorkshop didn't have any injectors in stock. Rather than have the car off the road for a while, whilst waiting for refurbishment of the originals, I bought a set of six from eBay and have had those tested and refurbished by MrInjector. I actually sent him 7, as I had bought a single spare previously. Of the six in the set, five were able to be resurrected, the sixth failed even after multiple attempts to clean. Luckily the single one was good so I have a complete replacement set.
James (MrInjector) says he sees a lot of these with blockages, due to the plastic filter mesh disintegrating. Even a tiny bit of the plastic will block the jets. He replaces with metal mesh.
These refurbed ones will be fitted to the car in the next week or two. I then plan to get the original set tested and refurbed. I'll keep two, as spares, and sell the others assuming that they can all be made good.
If anyone on the forum needs one or two, let me know. I'll offer them here before eBay.
