Yeah, have fun with this crap. My car has the same code to. Ironicly my mechanic says to replace the downstream O2 sensor. He says it is only reading "lean" and should be swutching back and forth, is that was yours said to? My upper O2 sensor was replaced in May.
Even more surprising my gas mileage has been low to since this code came about.
Looks like were in the same boat.
A downstream O2 sensor CANNOT cause a 0171 code.
You CANNOT get a 0174 on a Zetec.
