Code P04636???

Hello there folks, this is my first post here on your forum so forgive me if I make a fool of myself. I have cruised the site trying to find an answer about this code my superchips programmer says my 1999 silverado is throwing. A little history on the truck first. The truck has the 5.3, automatic, Z71 package with 199,075 miles, I have done litttle but maintenance and the programmer to alter it. I am the second owner, and bought it with 29,000 miles on it so I know it well
Two days ago the throttle seemed very lightly feathery, almost like it was starving for fuel or something. By feathery I mean almost like a surge, but almost unnoticable to someone who doesn't drive it everyday. I was thinking fuel filter, o2 sensors, fuel pump etc.. Thats when I remembered my tuner could read codes, so I plugged it in and it came up with P04636? Now I have a list of GM codes and this one is not on it. I have searched the internet ALOT and have lots of folks telling me its not even a code? I am getting frustrated, and can't afford to pay shop rate just to plug it in. Hopefully some kind soul here knows what this one means, because I would like to fix any issue before it possibly becomes a bigger one. Any help is much appreciated.
