You should probably start by stating what problems you’re actually having so that they can be addressed before wasting time tuning.

Well
I was cruising and got a SES light with code 44. Left bank lean condition. I had it earlier but i found a problem with HVAC vacuum leak. I fixed it, cleared the DTC.
Today after all I checked the engine for leakes with smoke machine and found one in optispark. I moded 94 non-vented opti to vented earlier as you can see above. I converted it back to non-vented and checked everything again. No leaks. Done.
But I watch throug the Eehack logs and I dont know if theese are normal parameters: (there is no much differences before and after vacuum fix in logs BTW )
MAF is 7.5 g/s at idle
IAC position sometimes 6 to 9 at idle
BLM is on
Also maybe smth is wrong
Here are logs

So, can anybody take a look? Or I need some logs from good working stock car. I will compare.

i haven't looked at your logs, but with the maf and iac so low you probably have another vacuum leak or unmetered air somewhere. the maf isn't reading much airflow, but the IAC is trying to lower your RPM. it's a very old car so anything rubber or plastic is suspect but also things like your 'intake elbow silencer delete' need to be rechecked.

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
