help with codes

[ooraceredgt]

yesterday i installed a lightning 90 mm mass air and had my program reburned to match the new mass air. after installing the new mass air i drove it maybe two miles and the car through the ses light and it begin to run extremely rough. i ran a scan and came up with a code P1132 "lack of ho2s11 switches. sensor indicates rich. see p2196" any help would be great

You sure the MAF is installed the right way? I've seen several people have them turned (rotated) one way or the other and run rich.
