Progress Thread No Clear 92 (Lack of) Progress thread

Me and the boy took the mustang to watch the races Friday night. On a hard pull I kinda felt a loss of power. Noticed I developed a helluva whistle. Gonna get a smoke tester. I see some on Amazon, but I don't wanna waste money on junk. Anyone have experience with Amazonian smoke testers?
 
Didn't want to wait on a smoke tester. I do still plan on purchasing one, but for for now I used a hand transfer pump from hobo freight and a cigar. Found zero leaks in the vacuum system.

I have gone over the car multiple times with it idling. Whistling seems to be coming from 70mm SR Performance TB. Makes sense I guess. Noticed it was hanging open just a bit too. Cleaned it up and got it to close fully. Still have the whistle. But throttle doesn't hang up anymore and I seemed to have gotten my power back.

1/2" smaller belt should be here today, hopefully that will fix my belt shavings issue and put my tensioner back into range.

Smaller belt is on. Kinda put the tensioner back in range. It was a bear to get on. Don't think I could go any smaller than that. Could this tensioner just be on the outs? Looks to be an OG Ford part.

TB is hanging open a tiny bit again. Idles a little high and whistles while stopped. Not every time, but here and there. I can push it closed with my finger and it idles normal and stops whistling. Next step may be to remove it and clean it up. It shouldn't be that dirty. It has less than 500 miles on it.
