P0171 and P0174 (mixture too lean) is a known design fault. Excessive oil is pulled into the air intake plenum above the engine from the PCV tube, and the accumulated oil causes the seals on the isolator bolts holding the plenum onto the intake manifold to fail and leak. The solution is to replace the isolator bolts (current ones have improved seals), intake/plenum gaskets, and possibly some other vacuum hoses. See Ford TSB 03-16-1.
It seems as though your Idle Air Controller isn't responding fast enough. If this isn't working correctly then it can cause the other two codes.
See "Related Questions" below for more on the isolator bolts problems, and more importantly, the fix.
The P1507 trouble code usually indicates an idle air control malfunction, while the P0171 and P0174 trouble codes signify lean fuel mixtures on bank 1 and bank 2, respectively. This could be due to issues with the mass airflow sensor, vacuum leaks, or a faulty fuel injector. It is recommended to inspect and potentially replace these components to resolve the codes.
To read the trouble codes in a 1993 Ford Topaz, you need to locate the diagnostic connector, usually found under the dashboard near the driver's side. Once you find the connector, you can use a code reader or jumper wire to extract the trouble codes, which will flash on the check engine light. Refer to a repair manual specific to your vehicle to interpret the codes.
To check trouble codes on a 1992 Mercury Topaz, you can use an OBD-I scanner or manually retrieve the codes by cycling the ignition key from off to on three times without cranking the engine, then counting the number of flashes on the check engine light. Consult a service manual to interpret the flashes into trouble codes.
The camshaft position sensor on a 1999 Saturn SL1 is typically located near the camshaft itself. It is often situated on the cylinder head or timing cover, close to where the camshaft rotates. Refer to your vehicle's specific service manual for the exact location.
DTC stands for Diagnostic Trouble Code, which is a code generated by a vehicle's onboard diagnostic system to indicate an issue with a specific component of the vehicle. These codes help mechanics and technicians identify and resolve problems during vehicle diagnosis and repair.
Codes called when procedures are grouped together are known as composite codes or bundled codes. These codes represent a combination of related procedures that are typically performed together as part of a single service or treatment.
Trouble code P0171 means: Fuel System Too Lean (Cylinder Bank 1) Trouble code P0174 means: Fuel System Too Lean (Cylinder Bank 2)

If your check engine light is blinking with the engine running that means an engine cylinder misfire has been detected . You will need to have your Ford Windstar scanned for any trouble codes to help diagnose and then repair the problem . You can drive it in to have it repaired , just drive in a moderate fashion ( avoid any rapid acceleration or deceleration because you can damage the catalytic converter )
