I have replaced the coil and brought a new set of HT leads and sparkers from JK. The only problem is the leads dont appear to be long enough so two of them had to have the old ones fitted again.
Now the bloody thing isnt running very well. Now here is my question is there a way to tell what plug isnt sparking? Is it safe to run the engine (becuase it does start), and then check the ht lead against the engine block or would it be better to just pull the leads one by one of the dizzy to see if that makes a difference? I would have thought that when I get to the one or two that are not working that there would be no noticable difference when i pull them. True or not?
Also should i use a pair of pliars to pull them of the dizzy?
Cheers in advance, we will get my van going between us all
