A6 codes 850

Hi,
Well i noticed the codes showed up when i did a flame trap service (replace and clean Throttle Body). I did try to clean with contact cleaner last month but codes went back, but i did not take the whole assembly out. Will take off the whole unit over the weekend and see what happens. New TPS at FCPGroton.com is about $45. Worst comes to worst i just might settle for a new one....Do you think this has something to do with black soots noticeable on my muffler? Cold(real cold) start sets gas fumes but goes away after warm up.
Thanks for the reply and have a great weekend.
