How many ohms resistance should a good plug wire show? I have one wire on my Vette that I believe is no good as it had come of the plug a little and was giving me a tip in hesitation and stumble. When I took it off it was all white inside. I cleaned it and put some dielectric grease in it and it seemed to clear up for a few days but now it is back and worse soI think the wire may have gotten damaged from having to jump the spark to the plug. I had been chasing this miss for 2 months. Only at low rpm say idle to 1200 or so. It was fine higher up which I found odd. I ohmed it today and it was 5.5. Any help is greatly appreciated.
