Generally when these codes appear it is due to insufficient fuel pressure. Test your fuel pump to ensure it is within specs. Have you changed your fuel filter?

You need to replace the intake upper plenum gaskets. There is two pieces, a top cover with one big silicone o-ring gasket and a lower half with six smaller silicone o-rings for the individual intake ports. You can buy these as a set, just for this job. Start this job by removing the wiper blades, then release all the screws, (including the ones that support the wiper motor), that hold that big black plastic valence at the back of the engine compartment. Pull that out of the way, you will have to pull the windshield washer hose through it, just disconnect it on the engine side, now you have access to the plenum. It's a pretty easy job now to remove and replace both halves, just a bunch of 8mm screws hold it all together. Take notes or digital pics along the way so you can pop it all back together. My only caution would be; when you have it apart, do not drop anything in the intake port! I always stuff kleenex in these while I'm working in case something slips out of my hands. Also, don't over tighten, it's all plastic. If you don't want to do it yourself, a shop should charge about an hour and a half, plus the codes must be reset and the van driven until all the monitors are ready.

Bank 2 is generally the passanger side. Recently, We have run across a few system to lean codes in Fords. We have ended up changing the O2 sensors.
