No you didn't, what codes?
P0171 is fuel TRIM system lean. That means the computer is working to lean the system.
The computer thinks that there is too much fuel in the A/F ratio. Some things to cause it include fuel vapor from the EVAP system dumping into the intake manifold. Have you checked the EVAP purge valve under the hood?
