Ive had problems with a slipping clutch on my 16v for the last month or two. Whenever I put my foot down the revs would go up but with little effect on speed. Got it fixed (new clutch) and got the car back on Friday but have noticed that the power band that comes in at 4-4500 rpm has gone. I have also noticed torque seems to be down. During the time of the clutch slipping, the car had a service, and the plugs and leads were changed. The leads I put on didnt seem quite as thick as the ones I took off so does anyone know if this will have a great difference? They were motoquip standard ht leads, so not performance leads or anything like that. Has anyone had the same problems. Would poor quality ht leads make such a big difference, and can anyone recommend a decent set. Also do performance leads and plugs make any difference at all?
