seslight after exhaust install, HELP!!!

[lmt0705]

just did a whole exhaust system on my 2000 ws6, pacesetter long tubes, custom 2.5s with 2 dynomax bullets over the axle,o2 simms and extentions. sounds great but about 5 miles into my first drive the ses light came on. it was running rough, I found a cracked plug on number 7 that I dropped during the install. I replaced all the plugs now the car runs great but the damn light is still on. I took it to autozone for a free code scan and it came up p1404 iat-b circuit malfunction/egr temperature sensor malfunction can anyone help me with this please???

Did you keep EGR or delete it during this install?

Is the IAT sensor plugged in (it goes to the air lid) and is the wiring ok?
