If your TB is gunked up enough in the right place, it would cause your throttle plate to stick and either not enough enough air, or too much, for what you need at that particular throttle position. I'd think that could cause a code for running too rich. I think the recommended cleaning interval was about 30K from what I saw on some other threads. Hopefully that's all it is in your case. Good luck.
