Is there really any point in posting issues when somebody tells me to check the tyre pressure.
I think it is known as humour. Doesn't hurt to have a giggle once in a while.

There is no point trying to teach a pig to sing. It doesn't work and it annoys the pig.

inlet manifold leak causing weak mixture ?
Yes very likely. I can hear this car whistling on the overrun, yet the brake cleaner test passes! Still investigating.
But as 50% of the inlet manifold is internal a brake cleaner test wont work . have you got a smoke generator ?

The brake cleaner test is for gaskets leaking to atmosphere. Any induction leak will create a vacuum and so will suck in the fuel spray. Any induced fuel will affect the engine note.

Yep I know that test
My point is 50% of the inlet manifold gasket is inside the engine so no amount of wafting brake cleaner around will test that for you.
You will have to have the manifold off to look.
You could always do a vacuum test will help diagnose a leaking gasket

Never try and argue with an idiot. They drag you down to their level, then beat you based on experience.
