Maybe you read it back in the 90’s when people were still afraid of computer controlled cars?
I agree, though: get a tester. It’s much easier.

That was my thought as well. And yes I read about it years ago in the 90's I think your comment about fear of computer controlled cars is right on. I still think a 20 dollar spark tester is cheap insurance and as you said less hassle
I believe the fear in the past was in the event of not having a solid ground when laying the plug on the block that somehow all that voltage could possibly jump to a nearby sensor or component thereby doing damage to the computer.
