I have changed both O2 sensors, plugs, wires, coil pack, and EGR valve. I am now getting an engine code of P2097, and I can't figure out what to do next. The van seems to run fine at driving speeds, but at idle it is very rough. The exhaust has a putt-putt-putt to it. All cylinders are getting spark, no apparent vacuum leaks, and have run injector treatments through 2 tanks of gas. Any further suggestions? Catalytic converter maybe?

This can be from a bad O2 sensor like a cheap one, an air leak at exahaust as well as intake, poor pcv operating system a leaky brake booster internally as well as contaminated fuel. Also if you have used silicone for anything in the engine it could have gotten on O2 sensors and screwed them up. It's best for a pro to do this so he can test stuff with his scanner like O2 unhooked for voltage etc. Pros can also do a mode 6 which may show something that you will not be able to do if you have an autoparts scanner.

No silicone has been used. When I purchased the O2 sensors, I made sure to get the best ones available at the parts store.

Looks like you 'll have to have apro look at it then as it can be a large variation of things. Make sure to check the air leaks which you can do like dut work not on throttle body correctly pcv system clogged etc. If not that then it's avoltage problem that a pro will need to check
