Replaced the crank position sensor, upstream O2 sensors, and the purge valve under the left side intake manifold.
P0446 code went away but I get O2 sensor codes without a CEL. Hopefully it's not an issue with the wire harness but once I get new anchors installed for my lift I'll start rotating the O2 sensors and see if any codes follow particular sensors or not.
On the bright side, the car drove much better. Very happy to be able to take her out for a spin again.
