2001 Ford F250 V8 Two Wheel Drive Automatic

yes I have a question on my econoline van.
I did a dianostic and it shows up a code PO175.
I already replace both oxygen scensors and MAF scensor and still getting the misfire, when I turned up the key.
I would appreciated if you can give any ideas on what to check and possibly the problem.
thanks

Two other thing to check for that could be part of the problem: If there is a vaccum leak it can also cause a misfire. Or it could possibly be a fuel injector that is clogged or a little plugged up.

P0175 is a rich code for bank 2 if anything to do with the injectors, it leaking or putting out too much fuel. I think the spec on them is 11-18 ohms across the injector terminals.
