Default did you remember to plug the MAF in? that might account for the CEL. As for the smell...

Does is smell like burning oil, or like Exhaust?

Default WOW... sounds like you are running extremely rich.

what Intake set up did you put on? did you change you BPV for a BOV? did you remember to connect the BPV? Did you put the MAF back in with the airflow the right way?

Get the codes read, if you haven't already.

Default My guess is there is a loose hose somewhere in your engine bay.

Go back and check your work. Is there anything left disconnected that you couldn't find an attachment for with the aftermarket intake?

On the side of the MAF there is a big arrow. Make sure the airflow is going in that direction.
