The codes are: P0172 System too rich Bank 1 P0175 System too rich Bank 2 P1443 Small or no Purge Flow Condition
The first thing to do is to check the fuel pressure. If it is too high, it will cause the engine to run rich. You may have a bad fuel pressure regulator.
The Throttle Position Sensor (TPS) could be causing the problem as well. There is a procedure for testing the TPS, but it is rather lengthy. If you go to the Public Library, you can get the MOTORS Manual for your vehicle in the reference section. That will have the test procedure.
Another possibility is a bad Coolant Temperature Sensor (CTS). This is a common problem.
You, also, can not discount the possibility of a bad PCM as well. Just don't throw parts at the problem. You would be better off paying a pro.
Also check the mass air flow sensor. If it gets dirty a false reading to the PCM could richen the injectors. Did you check you air filter??

Blocked hose between purge valve and FTP sensor 3. EVAP purge valve stuck closed I have read from others that say it could be just a cracked hose as well.

How do you fix trouble code P1443 on a 1997 ford ranger?
Diagnostic Trouble Code (DTC) P1443 indicates a failure in the EVAP canister purge valve circuit. The Evaporative Emissions (EVAP) Canister Purge (CP) valve controls the flow of vapors from the fuel vapor storage canister to the intake manifold during various engine operating modes. It may need nothing more than a good cleaning, vacuum hose connected or that is leaking, or may need more. I suggest you seek out the services of a good mechanic. Do not just throw parts at this. The code does not mean that any part needs replacing. It just means the EVAP system is being effected.
