   Done a bit of searching around and sounds like it's in limp mode I'm guessing? But still unsure of best way to fix it. when accerlating somtimes is gutless and suddenly kick in. What would be cause? Lambda sensors? If so replace then will stop the dodgy running?
   cheers

   what lambda's have you got plugged in? I think it could cause this if you have the post cat lambda plugged in instead of the pre cat one

   Yeah, sorry forgot to say I have the 2 lambdas, 1 of them is plugged in on the manifold ( green one ) and other one is in a sleeve in my engine bay
   Tbh I just went out and checked and they are all plugged in fine, the green one doesn't have much slack on though as its quite a distance to the lambda hole on the manifold, dunno if this will effect it....

   Sound's like lambda sensor related as you put manifold on and it's started doing it, could also be map sensor though.

    Have you checked lambdas yet? Been mentioned enough times. Try swapping them round maybe, I bet its that or an air leek at the manifold, did u use a new gasket?
