The 00' SS is aging...New problems? Hey guys..ill be quick and to the point.
Car throwing a P0107 Manifold Absolute Pressure/Barometric Pressure Circuit Low Input, it stalls out randomly especially with ac on and hick ups. AC on plus coming to a hard stop equals stall out but its intermittent. I will add it only seems to do it when hot outside(80+), I had this problem last summer and didn't fix it because it went away during the cold months. Wiring getting hot??
Diablosport tuner showing long and short term fueling to be perfect so I dont think there is a vacuum leak. Is it possible the map connector could be trashed?
It's gotten to the point where If replacing the connector does nothing I would let a chevy dealer find out wtf is wrong with it because I'm fed up. Knowing my luck it wont replicate it for the tech and they'll gladly take my money. As for the MAP reading I'm not sure what KPA the map should be reading at.
Parts that have been replaced
MAF- 1 week ago because it was malfunctioning
Throttle position- last year
IAC- 5 years ago
MAP- replaced when doing ls6 mani swap 5 years ago
Any ideas or experiences please share.

You'll need to get to the back pins on the MAP connector to track down the 5 volt reference and ground and make sure those are both good. It's going to be a pain in the *** though since the map is on the back of the intake.
Don't wing parts at **** just check the connectors and confirm what the issue is then attack it. If you have good power and ground/reference then you'll have some confirmation your MAP is toast.
FYI MAP ranges from 15 - 125 Kpa
I'm heads and cammed but I sit about 55 - 60 Kpa at idle, you'll vary by elevation and whatnot.

Just adding my input to your situation. Have you checked your battery voltage with the engine running? Sometimes when sensors start acting up its due to fluctuations in battery voltage when the car is running. The alternator or alternator wiring may be on the outs. If you havent checked your voltage give it a looksey hookup a volt meter and see if your getting over 12volts output on your battery you should be getting 13.5 or more volts output. If not have your battery and alternator tested. I had a problem chasing after what I thought was bad sensors with low input faults. I have a 99 M6 Z28 with 273,000 on the odometer bought the car in 2000 so I feel your fustration. Hope this tip helps you out or maybe someone else.
If you've only changed 5 parts in 20 years you are doing pretty good. Lots of people have changed entire cars multiple times in that time period.
I replaced a MAF, headlight motor and window motor in my first 17 years. Year 18 and 19 was much more extensive.
