Hint: the "B" connector contains the Terminal 30 (+12V) the powers the CAN bus and the INPUT signals (camshaft sensor).
So maybe a bad connection (ohmic) where the plug mates with the 'B' socket. Check and clean those connections.
The vacuum line 'maps' the fuel in the so-called LOAD module. That's the square area on top where the vacuum line plugs into.
On my S500, had similar complaints and after lots of tests, the ICM was determined to be at fault. Got a used one from a NY wrecking yard for $200.
