Mis - Fire

[coxy]

Hi,
Recently put some new denso iridium plugs and im gettin a mis - fire at high revs, do you think it could be a faulty plug?

[user2282]

i would check the plug gaps
and just check they are all the same ,then i would check the leads ,
as if they have been disturbed by changing the plugs ,one may be now faulty,
cheers

Have you still got the old plugs?

If so put them back in and see if it stops.

Could be a number of things but if you can give this a go it'll give you a place to start

Give me a call if you need any help

Yeah thanks Tina, one pain in the arse though, i changed the bloody leads same time as the plugs, so i guess i had better change them back as well!!!

Just helps to eliminate whether its your new plugs or not, I know its a pain but it's all in the process of elimination
