    I posted here not to long ago about a problem i had (http://www.saxperience.com/forum/sho...d.php?t=372622)
    thought i had fixed it but still is not going away.

    Coil pack and spark plugs have been changed, ran on a test at a garage and nothing had shown up, also changed the backbox as it started around the time i put it on, yet it still seems to be running horrid.

    I have checked all the filters and asked people i know who are mechanics with years of experience, yet no one can come up with an idea what it is not even the garage i took it to.

    Whats happening is one day it can be fine, the other day it will run horrible, as if its struggling to accelerate/gain speed and from time to time it will go to normal and work normal and if im driving along it will suddenly slow right down when this problem kicks in. If im sat at the lights the rev counter bounces when it is like this almost to the point it sounds like its going to die on me, is this a sign for the idle control valve?

    I just want to ask and check before i go spending out any more money as i cant really afford to keep spending.

    so yeh, any ideas ?

    Please, someone help!!! lol
