I was driving my viper the other day and everything was fine. I was not driving hard or aggressive. I then stopped at the store for no more than five minutes and when I turned it back on it was making this noise. I got it home and when I looked under the hood I saw the number 1 spark plug wire was damaged at the spark plug and was arcing off the motor. I switched the wire from number 2 to number 1. Still makes the same noise with or without it attached. I have not gotten the new spark plug wire in yet so it is currently running on nine cylinders. I don't think that is what is causing this and I'm not sure what is. Any ideas what the issue is here? I'm not sure how long I was driving with a bad spark plug wire. Oil pressure is good. Video is linked below. Please let me know what you guys think may be the cause of this... It is a 1998 viper RT10 with 50k miles.
