OK, disabled the VVL via unplugging the ESS.
Car worked fine after an initializations. Meaning while there was some power loss and change in driveabilty, no codes or nasty side effects.
The car seems to get quite a bit more thirsty with the VVT disabled, fuel economy dropped right away. Acceleration is also not as great, so is the ability to coast in (higher) gear, i.e. you need to downshift like you normally do on manuals :-)
As far as diagnosing my actual issue it made things WAYYYY worse. The issue - the rpm drops when taking out of gear, when running a/c even killing the engine at times. It did this even when cold, and MUCH more frequently.
