Code 41

I just picked up a code scanner and ran the codes after my check eng. light has been on and off for over a month now. It came up "41"-- system always lean. I got this code right after we rebuilt it. Changed 02 sensors and all was fine. Then, we moved to Denver(elevation??) and my S/C belt broke. Fixed that and ever since that dang light comes on after 5min. of driving. When we rebuilt the engine, we put on an S-flow 95 SC. The car has the stock MAF, a true dual exhaust, larger fuel pump. I wouldn't think this would warrant larger injectors, but I'm not sure. Any help would be appreciated!!!
