Replace fuel cap, EVAC hose is good, only thing left is the FTP Sensor which is located right on top of the fuel tank,only problem is...it's a Dealer part only >:(. I'm going to grab one out of a junk yard before i pay dealer prices for anything. sorry for the bad news.
Follow the troubleshooting tree that is associated with that code.
The p1443 code means a problem with the evaporative emissions system. There could be a problem with a broken or unhooked vacuum hose. Also could be a problem with the solenoid or sensor between throttle body and evaporative canister.

The above is copied and pasted from "The Thunderbird And Cougar Owners Club of America" "Straight from the service CD (mostly, I added a descriptor after the code) P1443=A problem with the EVAP purge flow system Continuous Memory Diagnostic Trouble Code (DTC) P1443 indicates an incorrect evaporative system purge control valve flow. Possible causes: -- Obstructed, open or cracked hoses between EVAP canister purge valve and intake manifold. -- Damaged EVAP canister purge valve. -- Damaged PF sensor."
