Question about 2004 Ford Freestar
Reset check engine light
Disconnect battery overnight. It will clear codes if you don't have the scan tool. It may run rough for a few miles while it relearns your car's routines.
Please rate as fixya if this solves your issue.

i will try to help. 171/174 indicates lean condition in engine. the mass air flow sensor is located in the rubber tube going to throttlebody. you can try to clean it. using mild carb cleaner safe for sensors, remove sensor from tube. spray clean the tiny wires located in the cylinder. do not touch them, they are very delicate. these engines are also notorious for leaking intake gaskets and faulty pcv valves. these will all set these 2 codes. feel free with anymore questions.

All you need is a 13mm boxed end wrench. The tensioner pulley is the one all the way on the bottom towards the rear of the van. You can reach it under the van. Slide under the van in front of the passenger front tire and you will wee the pulley. Put the wrench on the bolt and pull towards you to release the tension on the belt.

Mine is on too (MIL, with p0193), 2005 freestar. My dealer can't figure it out for some reason? So I went out and bought a code reader, will fix it myself!
Anyways it can be the fuel pressure sensor (approx $100 for part), the fuel pump, or regulator on the fuel line, not too sure what they are worth, and time for labour? I am currently looking for a test gauge to check the pressure in the fuel line to see if it is pump or regulator or sensor. Hopefully your service guys can run a few similar tests and determine what needs to go.
