This was really bothering me so i thought i would try one more thing.
I switched it on this morning and thought i would try one last thing!!
what i did was whilst the engine was running i pulled off the plug leads one by one to see if it made a difference!!
it did to all but plug lead number 2!!
When i took off lead 2 there was no dip in the engine revs or anything soooooooo put a new spark plug in and shes running sweet as a nut!!
Just wanted to say a huge thanks to all who offered there help and advice on this thread as its much appreciated.
And Mike................No more cold starts as if i keep doing this im going to cause myself problems like you said!!
