New logs. I drove a car all day on my business.
What I found
Sometimes LBLM and RBLM drops less than 110
AVGBLM too
Generally on deacceleration but not always
Checked, for vacuum leaks again. I have no leaks. I'm using smoke machine and I believe i would see if smoke came from somewhere.
The only thing I havent checked is brake booster. I'll check it later, but brakes seems to be okay.
I can attach those logs if needed
i know from experience that if your brake booster leaks on an fbody, your brakes barely work at all.. but definitely do check it.
Most likely the booster will be ok.
Idle is 900-1200
replaced the iac with used one
then it rised to 2000
used scan 94 95 to reset iac position
after clicking on that button about 5 or more times it has dropped to normal idle and IAC was about 10-14 steps
after restarting the car rpm is about 750-800
but target rpm is 650
IAC is about 20-25
Faulty IAC?

your TPS is at 1%.... why is your TPS at 1%? it wont try to attain your idle target if the TPS is open.
Good question. I'll try eehach to measure tps. Scan 94 95 always shows 1%
One more moment. The only leak i have is on the pic below. And I can do nothing with it. TB shaft.
its normal for it to leak a bit there. it looks like you haven't adjusted your idle screw. make sure your throttle plates are closed as much as possible (just not so much that they jam in the bore). after doing all this, pull your PCM BAT fuse for a bit just to make sure ecm memory is clear.
