I just got a call and it looks like the CTS bad...of coarse there is no part available until Tuesday so I'll be heading out to Pull and Save.
I'll let everyone know for sure.

Coolant Temperature Sensor (CTS) -
Located in engine coolant jacket on the driver's side of the block. To test, use a high impedance volt-ohmmeter. Resistance should be less than 1000 ohms with a WARM engine (examples = 212* would be about 185 ohms, 160* would be about 450 ohms, 100* (not warm enough) would be 1,600 ohms).
> What does it do? Adjusts the injector pulse widths (Colder coolant temperatures result in longer injector pulse widths and richer air-fuel mixtures). Compensates for fuel condensation in intake manifold. Controls engine warm-up idle speed. Increases ignition advance when engine is cold. Energizes the EGR valve solenoid to prevent flow of vacuum to the EGR valve.
