    just did full exhaust now ses light is on

    just did a whole exhaust system on my 2000 ws6, pacesetter long tubes, custom 2.5s with 2 dynomax bullets over the axle, o2 extentions and simulators, 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???

    P1404 is EGR Closed Position Performance - did you delete/block off your EGR? Tried looking it up in my Helms but it's not listed cause '01's don't have it. Try www.gearchatter.com
