Your idle actuator could also be bad. But I don't think that's the case if you just reset the adaptations.
Thanks for the reply. I'll check the throttle body to see if there's anything around there that looks like it could be what you describe. The MAF should be fine, I just cleaned it probably a couple weeks back. Is stabilant 22a available at an auto parts store such as advance auto or autozone? I've never heard of it.. guess a google search is in order.

Also, I'd still like to find out why the heck I can't access the adaptations in the DME/DDE anymore, that worries me more than anything else.
