Have a Ford 96 Thunderbird and code p1443. Some say replace purge valve and some say PCV. Where is the purge valve located. I've traced what I believe is vacuum line to a component on the right side of the intake. It seems to coming from the purge valve cannister if I am correct.
PCV valve would have nothing to do with it !
P1443 - Very Small Or No Purge Flow Condition
A fuel tank pressure change greater than a minus (-) 7 inches of H 2 O in 30 seconds has occurred with purge (fuel vapor) flow less than 0.02 pounds per minute.
Check for blockages between the fuel tank, EVAP canister purge valve and engine intake manifold. Check obstructions in the EVAP canister purge valve diaphragm and ports.
Suggest you buy a repair manual if you want to try an fix yourself .Or Go to ford web site Ford Oem1stop com an pay 29 bucks for 72 hours for repair info . Or take it to a qualified repair shop an have it smoke tested . Or goolge purge valve for a pic. an see if you can find it under the hood .

The positive Crank Case Ventilation (PCV) is coming from the intake manifold and usually goes to the Valve cover On that year it could be in the back of on the side of the Rocker covers ( Valve Cover) find the Vacuum line coming out of your intake and follow it, It should lead you to the Pcv

Have the throttle position sensor checked, might be faulty.
SOURCE: 1990 Ford Thunderbird SC with three trouble codes
CODE 13
Trouble Code 13 indicates that the exhaust stream oxygen content sensor (O2 sensor) is not responding as expected. When cold, the sensor is 'biased' by the ECM to about 450 millivolts. Before it warms to at least 600 deg F (315 deg C) it acts as an open circuit and when the ECM reads it, it reads the 450 mV bias. The ECM expects the sensor to warm in a short period of time and begin sending its own voltages.
