genuine plugs, genuine leads, genuine coil (in that order)
Thanks, I'd forgotten about advising coil too, appreciate the quick response!

2000rpm but seems fine when above 2500-3000rpm. He's changed leads and air filter but not plugs, and engine ticks over fine, no overheating etc.. I'm thinking sensor problems? Any advice appreciated so I can pass it on! Cheers.What Mrcheerful said could also be the maf.
Gap the plugs down to 1- 1.1mm from the stock 1.3 also.
