Thanks for that,
I used Bosch super 4's and non oem leads, updated 8mm... The car was running poorly before I replaced plugs and leads and the cid you described broke....oem leads are seriously expensive but did not realise replacements would be a problem otherwise would have paid the amount.
Am going to get the timing looked at to see if that's the issue and will check for leaks....
The miss does disappear when you rev the engine up...
