HELP!

2005 Ford Focus • Automatic • 66,000 miles

I got my 2005 Ford Focus Detailed today. After I picked up my car the CEL was on. I took it to Pep Boys and had the free code check done. The device said P0171 System to lean bank 1.

1. What could be wrong
2. Could the Detailing cause this?
3. Did they damage something to my car?
