Fiddle,
I read about not doing it that way and why not years ago. Don't remember where I read it. or what possible issues could arise. But most likely possibly harmful to the computer system. So I have used a spark tester every since. Cheap insurance.
I am sure you could find reference to it on the web

Sorry, but this is simply not true.
Just think about it...grounding the plug is doing the exact same thing as happens in the engine block.
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.
