"Ran Fine When I Pulled It", Yeah Right!

The only thing more mystifying than how many people don't know a bad running engine when they hear one is how many people say that
could it be, that the guy was so dam dumb, he thot it was strong ?!

My neighbor pulled in one day with a car he had just bought and said how great it ran.
I said "Not bad for a V8 only running on 6 cylinders" (I could hear it from my house)
Lucky for him I popped the hood and found the 5-7 plug wires reversed.
This is exactly why I don't get involved in posts where the poster says the car runs great except for this or that, because a lot of people don't have a clue and will swear up and down it runs great.
