Today I was having engine issues, the car started sputtering on me so thought it might be an electrical issue because I'm having issues with my vintage air and radio. Anyway, I parked the car on the side of the road and while the engine is still running, I opened up the engine hood and with one hand holding the hood open I touched the spark plug cable at the back of the coil with my other hand to see if I could wiggle in or something. As soon as I did I got electrocuted. Is that normal? I don't think I touched anything metal just the rubber wire, not sure I want to try doing it again to find out though.
