As the title states, my 2001 Sport Trac is throwing codes for lean bank 1 and lean bank 2. It's obviously the V6. Haha. Automatic with a 196,xxx miles on the clock. When I start it, it stumbles like crazy (hot or cold starts) and almost dies. Once it gets passed that, it runs perfectly fine. Unless, you try and go passed roughly 75% throttle. It just falls on its face and pulls a lot of power. I'm thinking clogged fuel filter, vacuum leak or warped intake manifold.
