C/E light says "Too Lean on Bank1 and Bank2"
So what could my problem be? I just bought it mine. Its a 2003 Ford Expedition Eddie Bauer Edition, 4x4. 5.4L Engine Code L. So, I put about 80 miles on it since I got it, and then the C/E light comes on. So I scan it, and a buddy tells me that it is probably too low on gas with the trash in the tank. So I fuel it up and clear the code. I get it down to about 1/4 tank, and it comes on again. So, I put a little over 10 gallons in it today, and I am going to swap the fuel filter. On the way to work today though, I did notice that uphill, It seemed like it misfired like crazy, or mabye shuddering. It was a strong symptom whatever you would call it, but when I cleared the hill, it wasn't really there. I notice that I did release the throttle a lot when I cleared the hill, but I pushed it again on flat ground and it didnt do it again. When I change the fuel filter I am also going to throw some lucas cleaner in there too. But I am thinking maybe clean the MAP sensors and all the air related sensors as well, and get all of that over with. What do you guys think?
