Thanks, you were totally right about that. The instruction manual some of us has is incorrect, it says to check the white wire at terminal D (wrong!). The pink wire at terminal B is actually the one to check.

This typo put me on a goose chase for almost 2 days. The ignition was actually fine, and it turns out the problem was fuel delivery. I ohmed all the injectors, they were good, then checked fuel pressure and it turned out to be the fuel pump. Car is running fine now!

"Goose Chase".....I told you 3 days ago to check your fuel pressure, which was my first reply to this thread. But you were all hung up on your code41, ignored my advice, and didn't step back to examine the fundamentals:
<<AIR>> <<FUEL>> <<SPARK>>

BTW, your welcome...Next time you have a problem with your vette, you really should take it to a competent mechanic....or you'll end up replacing the heads when the problem was just low air pressure in your tires.
