check engine light

so i went to the track tonight, and got 2 good runs in,

but it ran kinda rough, and check engine light came on on my way home,

i got a KOEO

Code 18 ( IDM circut failure or " SPOUT " grounded )

Code 28 (Vat Sensor out of range " self test range " )

Code 48 ( loss of IDM signal )

What do i do about any about the codes i got ?!

I got a 2.4 60 ft time and a 2.6 time

One 9.8 1/8 mile, one 9.9 1/8 mile

Both running rough, and these codes, and stock motor just turbo swap !! ..

Let me know !!
