engine light problem, 3sgte engine light stay on , sometimes off Options

[Needles]

i did bypass the cpu in the back and add the 2 resistor a, all is connect good,

but my engine light up after...
- right when i start the car
- 4-5 sec after i start the car
-doesnt show up until i get to 2500 rpm

sometimes my engine light close and when i press gas after that (whit engine light close) i have a complete cut off very short time, and that think make my engine twisting on the engine mouth (it give a big kick) when it goes back (0.5 sec approx)

i didnt cut the rest of the wire from the cpu that goes to the engine bay, just in case, but i think they useless now that i bypass code54 direct the back of cpu ?

does someone know what it can be?
