Technical punto gt still struggles to rev

[bolkyboy]

hello again

i have my fiat punto gt turbo 1.4 still and i got the same problem still.

wen ever i go to give it some revs in neutral its struggling to build the revs up. it ildes fine .


i have put on the car :

new lambda sensor

new camshaft sensor

sent the injectors off for cleaning and testing

but still no joy.

the only mod it as got is the k&n air filter.

friends have suggested to me it could be either coil pack and leads or fuel pump is not sufficent enough for the car.

can any1 give me and ideas as to what the problem could be ?

1 other thing is it normal for the ilde control vale on the top the engine to buzz wen the engine is not running as before it was and i carefully took it apart and the mental ring inside was shattered so i replaced the whole thing

all your help would be much appreciated

thanks
bolky
