I agree and that's what pisses me off!

More likely the other way around, if you have a mixture issue, the PCM should disable MDS while the condition is present.

A mixture issue? Do you have any ideas in mind?

Which O2 sensor code are you getting? If it is just whining about catalyst efficiency, that should affect running much at all. If it is the front O2 sensor, that has a more profound affect on how the engine runs. A relatively easy test is to simply unplug them (both front O2 sensors) and see if the engine runs any better. If it does, replace the sensors. (Denso, or NTK please, seems dodge has real issues with Bosch sensors.)
