I drilled my airbox yesterday, about 15 hole sin total round the bottom of the box, side (Wing) and near the funnel that goes to the bumper.
Since this if i accelerate at low revs (1 1/2 thou)with full throttle (In gears 4th and 5th, none of the others mind) the car hesitates, misfires and jolts along and nearly cuts out, as soon as i lift off full, say only a slight bit the car accelerates as normal.
Any ideas ??
The car did this when i fitted a 57i, so i took this off and resorted back to the standard box, this sorted it, until now i`ve drilled the Box !!
