Uhhh.. That's crap. The copper cap is just for the IAC. It is supposed to restrict the air going through the IAC passage. However, the hole should be big enough to let the engine idle properly. A complete passage blockage wouldn't let the engine idle properly. Did you read the part about drilling the hole wider so it idles correctly?
No need to call something a "lie" just because you didn't get it to work the first time.
You just disrespected Ray McNairy. Bad mojo! :p
