2006 range rover Westminster cold misfire

Good day all!!

I have a 2006 range rover S/C westminster edition. I am experiencing cold misfires on just about every cylinder, however once the engine warms up she runs smooth as silk. Anyone else experience this problem? Doesn't appear there is bad compression on any cylinder. Also the rover shop I have taken it to had one with a similar issue. They have tried replacing cool packs, wires, tune up, and injectors with no luck. They did day they saw a bit of low fuel pressure so they are replacing the fuel pump to see if that helps. Does anyone have any ideas??

Thanks

Jon

Is it throwing codes? If not it would be a fuel related issue as a cold start problem. Have you done a fuel pressure test?
