donot know its idles kind of rough just like to what p0174 mean and what to do
I have the same problem with my 2003 Expedition. I have the exact same code appearing. I tried to clean the MAF sensor as described in another web posting, but that did not work. I also tried to uplug the sensor temporarily to help diagnose, as suggested in a repair manual, but that did not affect the problem either. Any suggestions appreciated.
