I would say NGK plugs for yours, they are under £8 at my local factors but Bosch are ok,I got a set of those for under £7 as I needed a particular type for the later coil pack engine(thanks to fordy),leads can look ok but can still be dicky,a new set will almost certainly improve matters,but if its running acceptably well leave them,also try cleaning the distributor cap contacts and rotor arm tip,made a difference on my old Ally,bit tricky to remove,I found it easier when moving the fuse box thingy to one side,well done on the old TB,Ive seen recon ones for £65 to £100+ on e-bay and cheaper from the breakers of course,be thankful you havent the bosch type! they can be a pain and much more expensive but thanks to some great folk on here I may have fixed it ,regards Dave. P.S.i think 1.3 is a different T.B
