I have an 05 6spd just recently hit the 100k mark, I keep her well maintained and currently have the aem cia. On my way to work this mornig the cel turned on so I scanned her once I got in the garage and had etc p0172 rich on bank two. Ive noticed her idle is a little ruff but i figgured it had to do with the milage but other than that she runs beautifuly. Im hoping that its reading rich because I havent redlined her in a week or two now and it may be a deposit or aan error. As of rite now the cel is still off but the driving cyle may not be complete. has anybody delt with this and am I going to have anothher project on my hands because of it?
Any advice or experience would be greatly apreciated.

I'd say wait a day or so and see if if the CEL comes back. There are a number of things that could have caused it to run rich for a brief moment, but unless it's a continuous thing, I wouldn't stress over it.

If it comes back on.. check you intake and air filter. A clogged or dirty air filter can restrict air, causing it to run rich. Also check/clean your MAF..
