[adamg1]

hi there folks i had some helpfull info last time on the problem i had with my clio missing mainly when cold,i changed the leads to magnecor's no diff so then changed the plugs to bosch super 4's,problem solved or so i thought,it was fine for over a week but just lately it has started missing again on the odd occasion when cold,it lasts a few mins then sorts its self out,just abit emmbarasing as theres usualy traffic behind me when im spluttering down the road,its happens around the 2k rev range.
any help is always welcome.oh its a 2000 clio 172.
thanks
