Check engine light
My check engine light came on, I figured it was an O2 Sensor so had the code pulled. The code is P0174 which I was told was the O2 Sensor but the place I talked to could not tell me which one. How many O2 sensors are there on a 4.6 and does anyone know which one this code is for?

RE: Check engine light
I have a '98 F150 with a 4.6, and just tackled this problem yesterday. I had codes 171 & 174...fuel sys lean banks 1 & 2. For me, I had a hole in the rubber elbow coming off the PCV valve. I took the neg lead off the battery (to reset the ck eng light), changed out the elbow and have been good for 30 miles so far.
