Re: Ranger idle problem?
Mine did that too. It would stall in cold weather, not so much in warmer weather. The p0171/p0174 means you have an air leak somewhere. Find that leak! Mine leaked mostly at the upper intake manifold gasket and the fuel rail gasket, so changing those fixed mine. No more stalls. Yay! Replacing the IAC, DPFE, and MAF did nothing to help mine. Small air leakages also come from vacuum & PCV hoses.
