Check Engine Light On After Upgrade ?

[SF Lex]

I recently upgraded my throttle body, with a extension EGR plate, mass air sensor, plus a cold air intake, all BBK. All runs well, but the check engine light is on? Did anyone have this same issue ? Wondering how i can turn it off? or if anyone has any experience and knows why ? Will it come back on after i get it turned off ? Not sure what i have to do now.
Thanks

Not sure what i have to do now.

Pretty simple. Run the codes, and see what's wrong. Then go from there.

There is a jumper wire method to run codes, or just buy the reader

DID you plug the MAF and EGR sensor back in?

Dump codes sticky

Look at the top of the 5.0 Tech forum where the sticky threads are posted. One of them is how to dump the computer codes. I highly suggest that you read it and follow the instructions to dump the codes. http://www.stangnet.com/mustang-forums/threads/how-to-pull-codes-from-eec4.889006/
