[ROVERNET - UK] SD1 Problem

[Lewis, Joseph (Michael)]

Hello fellow Rover enthusiasts -- 
I have a problem and I hope someone can help me solve it. MY federal SD1
with fuel injection recently started running very rough. It feels like I
lose a cylinder or a bad firing miss. It doesn't occur during cold
starts but within 3-4 minutes it occurs. The loss of power is dramatic
needless to say. 

I changed the wires, plugs, cap and rotor but this didn't solve it. 

Any ideas, guesses or experiences with something like this? Thanks for
any help.
