Question Why dont I have a check engine light?

I bored it, stroked it, but in the XE 230-236, SVO 30 injectors. Removed A.I.R. E.G.R AC and replaced nearly every componet in the motor. and the car is still running on BONE STOCK tuning.....
And the only time i get a check engine light is if i let it idle for awhile. and as soon as it is off idle it goes away. I expected my dash to be lit up like a christmas tree, even with OBD -1.
