Hi NAM Gurus....

I'm the happy new owner of a used 2003 MCS. I'm in love, but (of course) I have a puzzler.

Shortly after I got the car, I got the dreaded SES light. I've been reading the various threads with interest, and finally bought an ODB II reader. (an Actron CP9125 that was recommended in another thread).

And the Magic Code is: P2096

I found a single mention of this code in another thread: http://www.northamericanmotoring.com...5&postcount=10
But the thread was old, and I wasn't sure I could rely on it.

I found an old web page that listed the code as:
"P2096 or P2098 Post Catalyst Fuel Trim System Low Limit "

Any tips on what this might be and how I might make the light go away (other than tape over the light).

Oh... and taking it to the dealer isn't really an option (900+ miles away, no roads, welcome to Alaska!)
