hi, i wondered why is it that in my mondeo manual, the plug gap is listed at 1.3mm, but on some forums, a gap of only 1mm is recommended, which is a big difference.
they can't both be right, surely? also, am i correct that a gap that is too small can cause a low rpm mis-fire, and a gap that is too big will cause a high rpm mis-fire?
thanks for your replies!
