Hi, Can anyone help please? I have a Seicento 2001 1100cc. It runs fine but someimes when warmed up it idles poorly and may stall. It has had the coil packs replaced. The OBD codes are:- P0201 cylinder 1 injector problem, P0203 cylinder 2 injector problem & P0300 random misfire. It has multipoint injection. Has anyone got an idea what the problem might be please?

Start by checking the earth connections.There is a know problem with early MPi ECUs, it may need repaired.

Cheers
