You're not getting enough fuel. You should check your fuel pressure. If you have enough fuel pressure, your injectors are probably clogged up. Run a lot of fuel cleaner through your tank when you put gas in and see if it makes any difference. Lucas fuel treatment is the best to use.

On your Navigator the most likely failure that will cause a lean condition on both banks is the PCV tubing. Start at the PCV valve in the passenger side valve cover and follow it to its connection to the intake manifold, and closely inspect the rubber elbows in the tubing for vacuum leaks.
