My expedition has a 5.4 Triton V8 I just changed all 8 plugs and replaced 4 new coil packs. I now keep getting the system too lean in bank 1 and 2 codes. I have since changed the fuel filter, 2 oxygen sensors, took out the MAF sensor and cleaned with brake cleaner, and sprayed vaccum lines with carburator cleaner. Please Help! Im about to loose my mind with this thing.
have the same problem?
