Hi all hoping you can help me out with my 1.4 mk 1, it runs sweet at high revs, rev too low and it jerks. I have taken it to my dad (ex mechanic and mk2 owner) and within 5 mins of a drive round town he has concluded spark plugs or ht leads, a google search has suggested possible coil pack needed. I am taking it too my dad tomorrow to get it checked over in the light (if it's plugs I will fit platinum, leads are a maintenance item etc) Anyone any other suggestions of what it could be? Suffered the same thing?
