It's fairy simple: as long as it's tight after throttle, idle goes down.

So you have a leak either across the throttle or after the throttle. Cracked phenolic intake stacks are common, as are leaky intake/head gaskets. Big brass throttle bypass valve can be removed and hoses plugged.

Pressurize whole system with shop air and check for leaks. Use max 1.0 bar.
Thank you for your time,
