Expedition fuel management problem
I have a 2000 Expedition with the 5.4L and I get an OBDII error code of p303 which is Cylinder #3 misfire. I've replaced the coil/sparkplug.....I also swapped the fuel injectors # 1 and # 3. It runs fine for about 100miles then spits out the P303 again. I put an analyzer on it and STFT B1 and B2 S2 are both running at 99%. Anyone have any ideas? I
