Trouble code P0131 means:O2 sensor circuit low voltage (Bank 1 Sensor 1)
Trouble is, I can't tell you what means.

According to this site:
http://www.check-engine-light.com/trouble-codes
the message is "O2 (Oxygen) Sensor Circuit Low Voltage (Bank 1 Sensor 1)". In the site there is additional information provided by a hyper link and describes provides addition information from owners of a Subaru that had these codes, but most codes are universal and standard and I think this one falls into that category therefore probably applies to what you saw on your vehicle.
There is additional information for an owner of a Subaru that experienced a problem when they changed out the exhaust header and states:
A P0131 is described as 02 Sensor Circuit Low Voltage (Bank I Sensor I). The first thing that comes to mind is where is the front O2 sensor now in relation to where it was prior to the header swap. If it's further down the pipe then it's possible the exhaust gases are cooling down a bit more than before. That's why I think someone suggested you wrap your header, that will help hold that heat in and possibly improve the exhaust gas temperature (EGT) readings at that O2 sensor.
Here's another link for the problem from a Chevy Geo. Again it reads like it could pertain to your problem and includes some things on how to recover from it but you're gonna need an OBD II scan tool of some kind to reset the code.
http://www.hotrodlane.cc/New%20LS%20...TC%20P0131.htm
All in all it sounds like a rare condition probably caused by your load and the conditions driving around Pikes Peak. I had a code some time ago after doing some mountain driving. I can't remember the code right off the top of my head, but I did reset it and have never seen it since. It's your choice if you just want to reset it and go on or do something else.
Too bad you are not close by or I'd be glad to let you use my OBD II Tool, no charge.

Hey Don. That is the same code I was telling you about when we were at Ami's Acres. Mine came in when we leaving the Summit on Mt. Evans. As others have stated it is an 02 sensor code. Mine went out about 3 days after it came in and I never had any performance problems with the engine. Jim

Pikes Peak and Mt. Evans both sound like the altitude. This is not a common code on the ISB engine. Stop by Autozone and see if they will clear it for you or power up and down around 25 times and it will probably clear.

It might be cheaper for you to buy a scanner and reset it yourself. Where I live they either charge $50 to $100, or tell me to disconnect the battery for about 10 minutes, then reconnect. I don't like the disconnect battery solution, because my truck has TWO batteries and then there's a chance things might have to be reprogrammed like me radio channels.
Here's the one I have and have used, but there are plenty of others with more features:

I paid $59.99 plus tax, but I think it can be found cheaper, plus there are others that are cheaper. I wanted simple because I didn't want to get myself in too much trouble.

P0131 OBD-II Trouble Code
Technical DescriptionOxygen O2 Sensor Circuit Low Voltage (Bank 1, Sensor 1)
What does that mean?
Essentially the same as P0136 and P0137, a P0131 code refers to the first oxygen sensor on Bank 1. P0131 means the O2 oxygen sensor's voltage remained low for longer than 2 minutes. This, is interpreted by the ECM as a low voltage condition and sets the MIL. Bank 1 Sensor 1 is located in front of the catalytic converter.
Symptoms
There may be no visible symptoms to the driver, other than the MIL (Check Engine / Service Engine Soon) illumination.
Causes
A code P0131 may mean that one or more of the following has happened:
Faulty o2 oxygen sensor
Short to voltage on O2 signal circuit
High resistance or open on O2 signal circuit
Possible SolutionsReplace faulty sensor
Repair short, open, or high resistance on o2 signal circuit
