Sounds like you have oil in the injector wiring loom to me.

Take the red plug off the ecu under the drivers seat and have a look for the tell tale black smudges in the plug.

if it is do i need to replace anything or just clean the plug?

You will need a new modified injector loom under the rocker cover. They're about £40

Also change your fuel filter as it may just be fuel starvation.
15 minutes to do if you have not done them before.
Filter lives under the rear wheel arch drivers side.
Get a decent filter as the cheap ones fall to bits inside.
I change mine everytime I do an oil change.

thanks people most helpfull cheers!
