Hi all
hope someone can help , my 54 plate ulysse is only firing on 3 once it has warmed up . When starting from cold it is fine .also the monocrhome display has gone, from what i can make out it states ?????????????????antipolution
thanks in advance

I doubt it is firing on 3 cylinders, probably just enters limp mode when warmed up.

Defo only firing on 3 / no 4 is not firing

Why would it run on 4 when cold but only on 3 when warm????

I think that is what he is asking....

Is it petrol or diesel?

Sorry for taking so long to get back too you , its petrol

Possibilities include ignition - leads - coil/s. I'd think an injection fault is unlikely, but it just might be the engine temperature sender.

leads are relatively cheap and easy.. worth hooking the plugs out too, (gaps..??)
