It is throwing the p0171 and p0443 what could it be and is it easy to fix and fairly cheep

Code 171 is fuel system too lean bank one. That means the computer can not make the O2 sensor switch from lean to rich and back. Could be the sensor, or a fuel problem.
Code 443 is a problem with the evap purge valve circuit. Could be the valve or a wiring problem. The purge valve vents fumes from the gas tank to the vapor canistor.

I got code PO 452, PO 443, PO 449 all EMS codes what do I need to replace and how hard to do your self?

The codes only tell the mechanic what to test, not what to replace.
You would need to get the shop manual for your vehicle to have the test instructions for each code.
Code 452 is a problem with the fuel tank pressure sensor circuit, 443 is evap canister purge and 449 is the vent valve circuit.
The evap system and those components would need to be checked out.

97 Mercury cougar xr7 v6. po443, po430, po171, po174,

Sounds like you have low fuel supply or a leak in intake system causing lean codes, check fuek pressure and volume first. Cat converter effeciancy could be caused by the lean codes, purge system sounds like solenoid failure, check for high resistance accross purge vent solenoid.
