What would you need to fix if you are receiving Trouble Codes P1507 P0171 and P0174 on a 2000 Ford Windstar 3.8 6 cylinder?
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.
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 )

I do not ever recall seeing this question! Be forewarned though, the base diagnostic trouble code (DTC) descriptions are very short & cryptic. But it's a good start to identifying the components/sensors/readings that are involved. See "Related Links" below for 2 sources of Ford OBD codes listings...
Just replacing a sensor that was the source of a 'trouble-code' doesn't mean the true *cause* of the problem was fixed. It's really important to research those trouble codes *BEFORE* replacing sensors. It's time to go back and have those codes read again and then learn about what causes them.

I'm not exactly sure about the 136 and 141 codes, but the 171 and 174 are symptomatic of a known problem with Windstar 3.8 litre engines. Those codes combined with rough idle are prime indicators of a leaking upper intake manifold involving worn out "isolator bolts". See "Related Questions" below for more
Stop by http://www.coloradofans.com there are different people that have had that problem. you can probably message them personally and see how they got to that problem. P0300= Random/ multiple cylinder misfire detected P0301= Misfire detected- cylinder #1 P0302= Misfire detected- cylinder #2 P0303= Misfire detected- cylinder #3 P0304= Misfire detected- cylinder #4 p0305= Misfire detected- cylinder #5 P.S. These are Diagnostic trouble codes, not vechicle id numbers.
Ford Windstar 98 The engine light went on a car mechanic said the cam sensor was not in its right position but fixed it After two days the engine light went again on What is it?
Where do you get explanations for Ford WINDSTAR error codes you have 2 codes PO171 and PO174 what do they regard?
The key here is that each warning light is trying to tell you 2 different things. They are not likely to be related to each other. Research each light separately. NOTE: Fix the *cause* of the trouble codes and the lights will turn themselves off. See "Related Questions" below for more about check engine lights & Windstar ABS systems
