I got a SES this morning after a hard acceleration.

I fired up my OBD software and found the code and reset the light, but I wanted to find out what the code means.

Here is what I got.
Powertrain - P071 - Fuel trim too...

I assume that because it happened at redline, the fuel trim was too lean, but I wanted to be sure. I have been running my current setup for 6 months and the is the first time it happened.

Thanks
