2001 Ford Ranger, 4.0L V6 engine, 68,000 miles - Check engine light went on and the store said it was Fuel too lean - mixture bank 1 & 2. When you start the car it hesitates and sounds like it is going up and down like to fuel is not getting there. Once it runs for a few minutes it runs fine, but begins again when you start the vehilce. I replaced the fuel filter, still happens.
