Thanks for the advice, taking off the throttle body was a much easier job than I anticipated. The IACV was indeed sticky, the underside of the throttle body was in a word filthy. Although not half as bad as some pictures I have seen of throttle bodies.
Anyway cleaning it has seemed to improve things no end though I can't be certain until I've taken the car for a few runs.
Anybody have any thoughts about spark plugs? I've currently got ngk's in the car but I've heard bosch are better for the coil pack Micra.
