For whatever reason, instead of the crankcase fresh air tube being routed to the engine's intake duct as shown in photo, it was routed to a manifold vacuum port (shown circled in red in photo). The car now drives and behaves like any other vehicle at idle and low rpm even with the a/c engaged. Has not stalled in the 200+ miles I have driven it after I rerouted the PCV and shows no sign of wanting to either. Also the 2-3 second wheeze noise after shut down is gone. Sounded like a dog's squeeze toy lol. Guessing that the crankcase was turned into one big vacuum reservoir...with no check valve. Some interesting dynamics going on there at idle and light throttle....
This car was not easy to drive at low rpm on one of it's good days and on a bad day it would stall/die and buck/jerk the driveline, esp. with the a/c on..... but once you started pushing the accelerator down, all was forgiven lol
Here is a before pic of the PCV routing in this link before the car left MMS 3 or so years ago to show the differences.
