If I could plug a computer in I'm sure it would tell me what the problem is but I don't have the technology for that care only for modern cars.
And I just talked with all the cuss words out there somebody would have had this issue before and knew what to do. I appreciate your time for obviously you haven't come across this problem before as I said the car runs perfect on the level six but not on the level eight. And the reason I'm keeping it is because it has a wasted spark system fitted to it. Which I disconnected it to see was it causing the issue.
