Im having a problem with a 95 chevy camaro z28
i recently installed taylor 8mm spyro wires and ngk tr55 plugs. the reason for this was i am getting spark at the plug boots itself on #8,#4 #3 and around my coil . i replaced my cap and rotor too with an accel from summit. what would be causing this i tried 4 different sets of wires and changed the coil too no difference . cleaned the boots and used dielectric grease and cleaned and checked all grounds it still does the same. is this common or did you ever hear of this and what else could i check

thank you for any help
speedy!:

 

Check that the grounds to the engine block are clean and tight.

 

If it is just a "halo" it is called a "corona". Go to NGK's site and get the straight scoop about it.
