anyone see anything wrong with these sm readings.

What's your fuel pressure on the line? Check your fuel pressure,

When was the last time you changed the o2 sensor?
 
43/44 no vacuum line on. I have replace every sensor/relay on the car in the last 3/4 months. I didn't have any problems, other then they are/were 26 years old

Stock chip? Have you tried to disconnect the ecm orange wire near battery and reconnecting it to allow the computer to "re-learn" Once you change any sensor / raise or lower your fpressure you should always allow the ecm to "re-learn"
 
Yes I have done that, chip is TT 93 pump 42 # . However I am running 100 octane full time

If the fuel has lead in it your probably throwing your O2 sensor out of wak the lead in the higher octane fuel will cause the oxygen sensor to fail or cause it to go bad little by little.

That doesn't take a gasket i dont use anything on there i just bolt it on. I have heard people using RTV on there but thats up to you.
 
ok went and made the vacum block gasket and replaced allthe vac lines the whistle is gone the missing seems to be gone didnt take for a run yet but sitting there at idle the blms are at 138 when i hit the gas goes to 128 -129 when i let of slowly goes to 138 steady then when the fans go on it goes to 150-160 does the same thing as soon as i put it in drive from 138- 160.so i know i dont have vacum leaks fix ed them .now time to check those pipes .
