There could be a vacuum leak downstream of the Mass Air Flow sensor or the Mass Air Flow Sensor is dirty or faulty. Try cleaning the MAF sensor wire elements and clear the engine computer code. After removing the MAF sensor, spray the honeycomb inside the sensor, or the air meter with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling. Inspect all vacuum and PCV hoses, and replace any vacuum hoses that have cracks, cuts, etc. If it has been a long time since you changed your Fuel filter, it may be a good time to do this as well. This could also be due to a faulty O2 Sensor.

Most likely a vacuum leak

If O2 Sensors are over 100,000 miles
replace them

Still check for leaks

Ford windstar check engine light comes on after stopping when starting to get moving again shows p0171 & p0174 codes why??


P0171 indicates a lean condition. The most common cause of this is a defective mass air flow sensor. Also check if any vacuum leaks. P0174 OBD-II Trouble Code


Technical Description

System Too Lean (Bank 2)


What does that mean?

Basically this means that an oxygen sensor in bank 2 detected a lean condition (too much oxygen in the exhaust.

Note: This DTC is very similar to P0171, and in fact your vehicle may show both codes at the same time.

Thanks.

Check engine light on


Generally when these codes appear it is due to insufficient fuel pressure. Test your fuel pump to ensure it is within specs. Have you changed your fuel filter?
