2004 Thunderbird 82 000 miles. The car ran great last summer, stored for the winter. This spring I put in a new battery. Now the car stalls at idle just like you turned the switch off. At highway speeds it sometimes has a loss of power. The car must be slightly warmed up before these problems show up. The check engine light comes on and code p0174 lean bank 2. Here is a list of things I have done. New plugs/coils, new fuel filter, new oxygen sensor sensor 2,1 smoke tested engine, checked the wiring, reseated grounds, cleaned the fuel injectors. Cleaned mass airflow sensor, then replaced. Sent the engine cpu to flagship one for repair. They sent it back saying no problem found. I don't really know where to look next, looking for suggestions.
