Yeah the rotor resistance was high, anywhere from 130Kohm cold to 30 Kohm hot. OVP relay was corroded inside, and didn't throw the ABS light due to that circuit being closed. New temp sensor has the same variance as the old, so the readings must not have to be identical as stated in the manual. Didn't swap that out.

So here's the deal: new oxygen sensor, good bosch non-resistor plugs, new rotor, distributor cap in great shape, new thermostat, vacuum lines like new. CPS tests 800 ohms cold, 880 ohms hot. Idle valve seems to work fine. Plugs are carboned up but not wet when stalled.

Car starts fine cold, idles/runs rough, sooty rich exhaust, stalls when operating temp reached unless rpms are kept up. There is still fuel flow and spark after stalling.
