It acts as if the choke is not engaging when cold.

Thanks for responding. Sounds like the best option is to take it in. Hoping that repair is less than $200. Retired and fixed income. Really like the car and hope to keep it for a few more years.

Find a buddy with a descent code reader that has live sensor data .. Hook it up BEFORE engine is started after sitting overnight .. Turn key on but do not start engine .. look at the CTS reading .. IF it is not the same as your outdoor thermometer, replace the coolant temperature sensor! .. CTS is responsible for fuel enrichment at colder temperatures, much like the choke was on the older carbureted engines... That Crown Vic should last you a good while, they pretty good vehicles!
