Just bought an 07 SS/SC for dirt cheap. Rebuilt title, after fixing some wiring that was not properly fixed right, I'm now onto the largest part, getting to run right. I'm getting codes
P0069- MAP Barometric pressure correlation
P0172- Rich bank one, and its running and smelling rich
P0315- Crankshaft position unlearned
(Sometimes a random intake performance code)
I just bought the car like this hoping an easy fix. Mods from what I can see so far, header, 3" exhaust, cheap little cold air intake and new filter I just put on, lowered, stage 2 clutch, poly mounts.
The car is very hesitant taking off, at half+ throttle it starts stalling out and the rest you will see in the video.
So far I have cleaned all vacuum lines, checked for vac leaks, took off throttle body and sprayed it out, replaced both skip and bar (Map) sensors and am still getting the code. I'm at a loss right now. Only possible other thing I think it could be is the vacuum actuator that the bar sensor runs to.
I've checked all power to map sensors and the actuator. Getting proper amount to all of them.
There is a mystery cable here getting 12v to it that I looked and looked and cannot figure out what it goes to, laying out under the TB area.
Here's a quick video

Also one of the wires I repaired seems to belong to the crank sensor that was poorly repaired and wouldn't let the car start when loose. Repaired it and I guess now that I may just need a case relearn for that once the car is running right possibly? The car is almost in drivable at the moment like this because any power to it causes it to cut out like its cutting fuel.
Any help would be appreciated. It's a great little car I just need to get it running right. Haha. Thanks a bunch for any help. Give me some ideas!
