Well got home.. looked at the plugs which look in a fab state.. i was well impressed with them given the milage i do...
anyways...
The fault was.... a small gasket failure between the maf and the airbox.. i think its due to the constant removal of airbox when i was looking at mounting up the charger.. anyways.. i have used a bit of liquid gasket and tightened it up before coating with some more instant gasket..i've let it dry and bamm.. no dodgy accelaration...
Also...
A quick update on the valver...
bought a new battery for her.. started and runs fine.. has a small issue with the total closure but i can deal with that..
going to rub down a few bits on the car that i have primed and then maybe throw some paint on her tonight
