right as you all know the coupe went eds3.5 back in march, felt good and went good bar the odd splutter on the odd occasion, so next up i went and stuck a xev inlet cam in and a uprated fuel pump as well as a tophat and a cdti airbox for good measure, that was two three week back now, felt really good up until tuesday not last week but week before, emmisions light flickered a couple of times on motorway doing about a ton, ill be honest it didnt feel 100% after that, half a week later on way to blackpool it flickered again after i back off from a decent speed as the motorway sweeps round to left, twenty mins later it stays on the rest of the night and day after till on way back from keithgley that goes off and eml comes on, goes down to work on moday(bh) and puts tech2 on, p0170 present and not present, clears them off and its not been on since has the light. car still feels crap, defo aint full potential, i get the half throttle splutter on the motorway which dont everyone or is there a way to get rid of this, on road it pulls like f*** but it feels to be holding back and can splutter when pulling away from ie lights etc. its ever since cdti airbox was put in, could the vxr airflow meter be faulty??? pipes are tight as even tho i dont like the setup 100%(foreman at work said it could be dragging air in) or could it be the wires thats been extended even tho mechanic from work says the solder and that were spot on that he did???
or any other ideas
remember i do have the oe dv blanked off and a bailey dv26
