   was driving along the other day and the saxo just lost power not completely but enough that it is not drivable at all, when it idles it judders like fuck, but then started it up the next morning and it was fine took it out for the day no problems, then last night it did it again, could it be the spark plugs? or air intake maybe?
   
   any help please would be greatly appriciated

   coilpack might be on its way out.
   Change the spark plugs see if that sorts it.
   
   If not, try get it on a diag machine or a loan of a coil pack.
   
   Could be shite petrol
   ^ doubt its that but could be.

   First things first, remove the airbox tube from the intake and see what happens, thats the easiest thing to try
   
   Then remove the sparkies and clean them (or replace)
   
   When you open the throttle, does the juddering stop?
