Lack Of Power And Rough Running

[Shorty7589]

I have a 2003, pre june 2003, 03 plate mondeo tdci 2.0 130, it has had the injectors replaced, fuel pump replaced, fuel filter replaced and injectors programmed, it starts and runs very rough like only on 3 cylinders or something but when you switch it off and restart it it runs a lot better but still missfires at mid to high revs, the fault code that comes up when started the first time and running rough is P0200, once stopped and restarted there are no fault codes, it has the EGR valve blanked off, i had it ticking over and when i unplugged the MAF sensor there were no changes at all, surely it should make a little difference as other cars when i've done this they've spluttered on then cut out, any advice/help would very much appreciated.

Thanks

P0200 is injector circuit malfunction & commonly is an electrical fault.

Any ideas as to where i should start looking?

MAF?

EGR?

etc

Thanks

Problem is that it's a bit of a generic code - google P0200 & you'll see a list of possibilities , I suggest you start with the easiest & cheapest first.
