The engine in question is a 4.3 W series - ?95 Jimmy 4x4 Vortec with OEM coil and module. I am very curious as to whether or not a bad ignition coil or control module could cause multiple arcs on many different ignition wires. Originally I thought it was only bad at the #6 boot but when I really examine it, it seems that the wires arc all over the place and on different wires. Is it possible to have this occur due to a shot coil, etc? I am getting a multiple cylinder random misfire code.
I¹ve never seen this before and these are very good ignition wires (Taylor
8.2mm Thundervolt) - they should rename them ?lightning bolt¹ because that¹s what they look like at night. Anyway, I did the wires with new plugs (the distributor, cap and rotor were all done last year also). I read somewhere that once in awhile there¹s a bad run of dielecetic grease. I did use the grease on the boots so I¹m exploring a ?conductive¹ grease as another possibility.Thanks for any and all comments. Andrew.
